A new and general procedure is described for a detailed analysis of time-resolved fluorescence depolarisation data in the presence of electronic energy migration. An isotropic ensemble of bifluorophoric molecules (D1-R-D2) has been studied to demonstrate its utility. Intramolecular donor-donor energy migration occurs between the two donor groups (D), which are covalently connected to a rigid linker group (R). These groups undergo restricted reorientational motions with respect to the R group. The analysis of depolarisation data basically involves the search for best-fit parameters which describe the local reorienting motions, the interfluorophore D1-D2 distance, as well as the mutual orientations of the donors. For this, the analysis is partly performed in the Fourier domain and the best-fit parameters are determined by using an approach based on a Genetic Algorithm. The energy migration process has been described by using Monte Carlo simulations and an extended Förster theory. It is found that ...
TY - JOUR. T1 - Femtosecond transient absorption of zinc porphyrins with oligo(phenylethylnyl) linkers in solution and on TiO2 films. AU - Chang, Chih Wei. AU - Luo, Liyang. AU - Chou, Chung Kung. AU - Lo, Chen Fu. AU - Lin, Ching Yao. AU - Hung, Chen Shiung. AU - Lee, Yuan Pern. AU - Diau, Eric Wei Guang. PY - 2009/7/9. Y1 - 2009/7/9. N2 - We measured femtosecond transient absorption of dye solutions and TiO 2 films sensitized with two zinc porphyrins (PE1 and PE4) to investigate the interfacial dynamics of electron transfer in relation to the dependence of cell performance on the length of the linker (Lin, C.-Y.; Lo, C.-F.; Luo, L.; Lu, H.-P.; Hung, C.-S.; Diau, E. W.-G. J. Phys. Chem. C 2009, 113, 755-764). For both porphyrins adsorbed on TiO2 films with S 1 excitation (λex = 620 nm), the transient absorption kinetics probed at 630 nm and 4.9 μm are complementary to each other because only the excited-state and ground-state species were observed at 630 nm whereas only the charge-separation ...
Two recently developed theories of electronic energy transfer/migration were for the first time applied to real protein systems for extracting molecular distances. The partial donor-donor energy migration (PDDEM) is an extension to the previously developed donor-donor energy migration (DDEM, F Bergström et al PNAS 96, 1999, 12477) which allows using chemically identical but photophysically different fluorophores in energy migration experiments. A method based on fluorescence quenching was investigated and applied to create an asymmetric energy migration between fluorophores which were covalently and specifically attached to plasminogen activator inhibitor type 2 (PAI-2). It was also shown experimentally that distance information can be obtained if the fluorescence relaxation for photophysically identical donors, exhibits multi-exponential relaxation.. An extended Förster theory (EFT) that was previously derived (L. B.-Å. Johansson et al J. Chem. Phys., 1996, 105) ha been developed for ...
A wireless energy transfer system includes a first energy transfer unit having at least one resonant frequency, a second energy transfer unit having the at least one resonant frequency, and a load. The first wireless energy transfer unit includes a first coil magnetically coupled to a first wireless energy transfer cell, and the second wireless energy transfer unit includes a second coil magnetically coupled to a second wireless energy transfer cell. The first coil receives first energy and through the magnetic coupling between the first coil and the first wireless energy transfer cell, the first wireless energy transfer cell is caused to generate second energy, wherein the second wireless energy transfer cell receives the second energy and through the magnetic coupling between the second wireless energy transfer cell and the second coil, the second coil is caused to provide third electromagnetic wave energy to the load.
Previous work using reconstituted membranes has shown that energy transfer can be observed in mixed assemblies of LH2 and RCLH1 complexes,36-38 but controlling the relative stoichiometries and two-dimensional organization of energy donor/acceptor photosynthetic complexes on a nanometer scale, and the locations where excitation energy can migrate between them, presents new challenges. For some time, it has been possible to construct nanoarrays of single types of photosynthetic complex, starting with the light-harvesting LH2 complex of Rba. sphaeroides,18,19,21 and later the RCLH1 complex20 and the LHCII complex of plants.22 In each case the function of the complex, in terms of fluorescence emission, was retained; for LHCII it was possible to directly image the ability of immobilized molecules of LHCII to switch between fluorescent and quenched states. For LH2, there were indications of long-range excitation energy transfer; 80 nm-wide nanolines of LH2 complexes exhibited energy propagation on ...

The development of fluorescent sensors for Hg2+ has attracted much attention due to the well-known adverse effects of mercury on biological health. In the present work, the optical properties of two newly-synthesized Hg2+ chemosensors based on the coumarin-rhodamine system (named Pro1 and Pro2) were systematically investigated using time-dependent density functional theory. It is shown that Pro1 and Pro2 are effective ratiometric fluorescent Hg2+ probes, which recognize Hg2+ by Förster resonance energy transfer and through bond energy transfer mechanisms, respectively. To further understand the mechanisms of the two probes, we have developed an approach to predict the energy transfer rate between the donor and acceptor. Using this approach, it can be inferred that Pro1 has a six times higher energy transfer rate than Pro2. Thus the influence of spacer group between the donor and acceptor on the sensing performance of the probe is demonstrated. Specifically, two-photon absorption properties of these two
Artificial Light-Harvesting Arrays: Electronic Energy Migration and Trapping on a Sphere and between Spheres A sophisticated model of the natural light-harvesting antenna has been devised by decorating a C60 hexa-adduct with ten yellow and two blue boron dipyrromethene (Bodipy) dyes in such a way that the dyes retain their individuality and assist solubility of the fullerene. Unusually, the fullerene core is a poor electron acceptor and does not enter into light-induced electron-transfer reactions with the appended dyes, but ineffective electronic energy transfer from the excited-state dye to the C60 residue competes with fluorescence from the yellow dye. Intraparticle electronic energy transfer from yellow to blue dyes can be followed by steady-state and time-resolved fluorescence spectroscopy and by excitation spectra for isolated C60 nanoparticles dissolved in dioxane at 293 K and at 77 K.

In this work we report the study of energy transfer between Nd3+ and Yb3+ ions in glasses with the 0.8CaSiO3-0.2Ca3(PO4)2 eutectic composition at room temperature by using steady-state and time-resolved laser spectroscopy. The Nd3+→Yb3+ transfer efficiency obtained from the Nd3+ lifetimes in the single doped and codoped samples reaches 73% for the highest Nd3+ concentration. The donor decay curves obtained under pulsed excitation have been used to establish the multipolar nature of the Nd3+→ Yb3+ transfer process and the energy transfer microparameter. The nonradiative energy transfer is consistent with an electric dipole-dipole interaction mechanism assisted by energy migration among donors. Back transfer from Yb3+ to Nd3+ is also observed.. ©2010 Optical Society of America. Full Article , PDF Article ...
Since the triplet-triplet annihilated upconversion (TTA-UC) materials work efficiently only in degassing organic solvents, it is of significance to find a new medium without toxicity and volatility and that promotes TTA-UC. Here, we firstly reported the effect of an OH-containing medium on low power upconver
The conservative and dissipative dynamics of a 2DOF, system composed of a grounded linear oscillator coupled to a lightweight mass by means of both strongly nonlinear and linear negative stiffnesses is investigated. Numerical studies are presented aiming to assess the influence of this combined coupling on the transient dynamics. In particular, these studies are focused on passive nonlinear targeted energy transfer from the impulsively excited linear oscillator to the nonlinear bistable lightweight attachment. It is shown that the main feature of the proposed configuration is the ability of assuring broadband efficient energy transfer over a broad range of input energy. Due to the bistability of the attachment, such favorable behavior is triggered by different nonlinear dynamic mechanisms depending on the energy level. For high energy levels, strongly modulated oscillations occur, and the dynamics is governed by fundamental (1:1) and superharmonic (1:3) resonances; for low energy levels, chaotic ...
Femtosecond transient absorption spectrometer Our femtosecond transient absorption spectrometer is a homemade pump-continuum-probe setup. The main femtosecond laser source is a Ti:Sapphire system from Spectra-Physics (Tsunami oscillator followed by a Spitfire regenerative amplifier). It delivers 50-fs ~0.7 mJ pulses at 1 kHz around 800 nm. Tunable pump pulses in the visible are produced by a noncollinear optical parametric amplifier (NOPA, Clark-MXR). A broadband continuum probe is obtained by self-phase modulation of a 800-nm beam in a CaF2 plate. Its time delay with respect to the pump is adjusted in a motorized optical delay line. The pump and probe beams are focused with parabolic mirrors and overlapped in the sample, kept in a 1-mm cell. The sample may be constantly displaced in two directions to avoid the re-excitation of a previously excited area. The sample may also be thermostated with the help of a water bath circulated through the sample holder. Fig 1 gives a schematic view of the ...

i) Photosynthetic organisms are exquisitely arranged so as to capture incident sunlight with high efficacy, and transmit the transient excitation energy to a reaction centre where chemical reactions are initiated. The energy-transfer mechanism is often described by semi-classical models that invoke hopping of the wave-packet along discrete energy levels and over considerable distances set in 3-dimensional space. These energy levels combine to form a large peripheral light-harvesting antenna coupled to individual reaction centres. Many attempts have been made to duplicate the essential features of the natural process, ignoring elaborate events such as self-repair and quantum coherence, and great progress has been made in understanding the basic energy-transfer steps. Mostly, these bio-inspired molecular systems have been studied as standalone entities in 2-dimensions, with little consideration given to longer-range energy transfer between moieties embedded in a solid matrix. We have built and ...
In the design of transcutaneous energy transfer devices variation in spacing between the coils results in energy transfer efficiency changes. These changes may have other causes. It is proposed to use an autotuning circuit and a voltage control circuit in cooperation with feedback from the internal coil in order to better maintain energy transfer levels as desirable. The feedback is typically provided via IR communication; however, when skin is highly pigmented, IR communication is inefficient. A method and system for using RF signals to accomplish the communication is disclosed.
The method of orthogonalized plane waves is applied to a calculation of electronic energy levels in potassium, using a potential obtained from a self-consistent field. The energies of twenty-four states at four symmetry points in the Brillouin zone have been obtained. The lowest band is dismissed in detail and the qualitative features of the density of states are presented. Departures from free electron bands are found. Comparison of higher bands with some other calculations suggests that certain features of band schemes may be reasonably independent of the potential used.
This thesis describes studies of collisional energy transfer in two small, combustion relevant free radicals. Collision-induced electronic energy transfer (EET) between the B2r and A2 fj. states of the CH and CD radicals was investigated with the collision partners He, Ar, H2, N2, CO and C02 using a dispersed laser induced fluorescence technique. CH or CD radicals were prepared photolytically, and excited into a single rotational level in either of the B2::E-, v ==°or A211, v =1 levels. Wavelength dispersed, time-resolved emission was then recorded from the initial and product states. Microscopic rate constants for vibronically resolved transfer between the two electronic states were determined for each collision partner, as well as those for vibrational energy transfer in the A state and total removal to other, unobserved states. EET was demonstrated to be ubiquitous, occurring with all of the collision partners used in the study, with varying efficiencies. These relative efficiencies ...

Methods and apparatus for providing a sufficiently stable power to a load in an energy transfer system that transfers energy from one side of a physical boundary to another side of he boundary. In one example, a power supply and a primary winding are located on a first side of a physical boundary (e.g., external to a body), and a secondary winding and the load are located on a second side of the physical boundary (e.g., internal to the body). A primary voltage across the primary winding is regulated so as to provide a sufficiently stable output power to the load notwithstanding changes in the load and/or changes in a relative position of the primary winding and the secondary winding. One aspect of the invention relates to energy transfer methods and apparatus for use in connection with the human body. In particular, one example of the invention includes a transcutaneous energy transfer (TET) system for transferring power from a power supply external to the body to a device implanted in the body.
From Dynamic Equilibrium to Photoinitiated Processes: Tracking Condensed Phase Dynamics. Abstract. Many important processes in chemistry and biology occur in the solution phase, including protein conformation changes, energy transfer processes, and proton and electron transfer reactions. Understanding condensed phase dynamics is essential for describing and predicting these processes, which is why it is a prevailing topic throughout the scientific community. In this talk I will discuss two different research topics that explore different processes in condensed phase systems. The first focuses on understanding ultrafast photoinitiated processes of photosystem I, a light harvesting complex that catalyzes oxygenic photosynthesis. Here two- dimensional electronic spectroscopy (2DES) gives remarkable insight into the very first steps of light harvesting in photosynthesis. The second explores dynamic equilibrium in a fluxional metal-carbonyl complex. Here two-dimensional infrared (2DIR) spectroscopy ...
Fluorescent labels are provided employing energy absorber/donor components and energy acceptor/fluorescer components joined together by a spacer which comprises sugar phosphate monomeric units, particularly ribosyl phosphate monomeric units, where the sugar groups are free of active hydroxyl groups. Particularly, an energy transfer component is substituted at the 5 position of the spacer chain, while the other energy transfer component is substituted at the 1 position of the 3 terminal ribosyl group of the label forming an ET cassette for linking to a nucleic acid sequence with any compositions. By employing combinations of ET components, with a common energy absorber/donor and different fluorescers, one can provide for families of labels which can be tagged to any target molecules and which can be excited at a single wavelength and fluoresce at different wavelengths with large Stokes shifts. The compositions find particular application in sequencing.

Abstract: According to the theory of quantum electrodynamics, transfer of electronic energy between molecules occurs through the exchange of photons. The nature of energy transfer is highly dependent on distances between molecular centres involved in the transfer process. At short distances photons have a virtual character and molecules are coupled by longitudinal as well as transverse components of the field (with an $ R^{-3} $ dependence on the coupling). As the distance of separation increases, photons take on a more real character and coupling is dominated by transverse components of the field (in the far-zone limit the coupling has the usual Columbic $ R^{-1} $ dependence on separation). Of particular interest is the intermediate- zone where the distance separating the molecular centres is approximately equal to the reduced wavelength of the mediating photon. In this regime, electronic coupling has a separation dependence of $ R^{-2} $.. After a brief introduction to electronic energy ...
A series of single-phased emission-tunable Na0.34Ca0.66Al1.66Si2.34O8:Eu2+,Mn2+ phosphors were successfully synthesized by a wet-chemical synthesis method. Photoluminescence excitation (PLE) spectra indicate that the phosphor can be efficiently excited by UV radiation from 250 to 420 nm. Also, NCASO:Eu2+,Mn2+ phosphor exhibit a broad blue emission band at 440 nm and an orange emission band at 570 nm, which originate from Eu2+ and Mn2+ ions, respectively. Therefore, overall emission color can be tuned from blue to white by increasing the concentration of Mn2+ ions in the host lattice utilizing energy transfer from Eu2+ to Mn2+ ions. This energy transfer phenomenon was demonstrated to be a resonant type through dipole-dipole interaction determined with the help of PL spectra, decay time measurement, and energy transfer efficiency of the phosphor. These results indicate that NCASO:Eu2+,Mn2+ can be a promising single-phased white-emitting phosphor for white-light UV LEDs.. ©2013 Optical Society of ...
The ability to convert between molecular spin states is of utmost importance in materials chemistry. Förster-type energy transfer is based on dipole-dipole interactions and can therefore theoretically be used to convert between molecular spin states. Here, a molecular dyad that is capable of transferring energy from an excited triplet state to an excited singlet state is presented. The rate of conversion between these states was shown to be 36 times faster than the rate of emission from the isolated triplet state. This dyad provides the first solid proof that Förster-type triplet-to-singlet energy transfer is possible, revealing a method to increase the rate of light extraction from excited triplet states. ...

Notes. If an MCD calculation is run, the transition densities obtained in the TDDFT calculation are saved to TAPE21. For large molecules this can result in a very large TAPE21 file.. An MCD calculation relies on the excitation energies and, in particular, the transition densities that result from the preceding TDDFT calculation. If the results of the TDDFT calculation are poor then it is likely that the results of the MCD calculation will be poor. It therefore should be kept in mind that most TDDFT calculations will make use of the Davidson method for finding the eigenvalues and eigenvectors of the TDDFT equation. The Davidson approach involves some approximations that can lead to some variation in results with the applied parameters. The most important example of this is the fact that the results vary depending on how many eigenvalue/eigenvector pairs are calculated, ie how many transitions are selected through the LOWEST keyword. The variation is small for the eigenvalues (excitation energies) ...

A model has been derived to treat the multistate curve-crossing problem which often arises in diabatic representations of scattering processes. Transitions between diabatic states are assumed to occur only in the vicinity of curve crossings and the probabilities are evaluated semiclassically. Otherwise the nuclear trajectories are treated classically except for tunneling through long-range potential barriers taken into account by the JWKB approximation. Closed channels are included on an equal footing with the scattering channels. The model is applied to the problems of symmetric associative (and dissociative) ionization and excitation transfer in collisions of excited helium with the ground-state atom, using the diabatic representation for the Rydberg states of He|SUB|2|/SUB| presented in the preceding paper. The electronic coupling of the repulsive diabatic states in the continuum yields much larger ionization cross sections than does direct vibronic coupling of low-lying adiabatic states to the

In some cases when the generated stress is immense, there is a rapid energy transfer through the dense and ordered packing of molecular single crystals and they are self-actuated by elastic deformation and/or by a ballistic event. This self-actuation phenomenon of crystals is termed thermosalient effect (Hüpf-Effekt) and is extremely rare propensity of certain crystalline solids capable of bending, twisting, curling, rolling or locomotion [2]. These systems are a prototype materials for novel, environmentally clean and efficient thermal-to-mechanical energy transformation. The capability of rapid energy transfer through the dense and ordered packing of single crystals evolves as a new platform for efficient dynamic elements, including artificial tissues and microfluidic elements. The fast energy transfer secured by efficient coupling between the thermal energy and mechanical energy stand as their main assets towards the design of fast actuators. The thermosalient effect is often accompanied ...
