• quantum
  • Then, in using the multiconfiguration time-dependent Hartree method coupled exciton-chain vibrational quantum dynamics are accounted for. (ebscohost.com)
  • A general formulation of nonperturbative quantum dynamics of solutes in a condensed phase is proposed to calculate linear and nonlinear vibrational line shapes. (ebscohost.com)
  • Such varying molecular geometries can also be computed, at least in principle, by employing ab initio quantum chemistry methods that can attain high accuracy for small molecules, although claims that acceptable accuracy can be also achieved for polynuclelotides, and DNA conformations, were recently made on the basis of vibrational circular dichroism (VCD) spectral data.

  • polarization
  • High level of polarization (linear, elliptical or circular) High collimation, i.e. small angular divergence of the beam Low emittance, i.e. the product of source cross section and solid angle of emission is small Wide tunability in energy/wavelength by monochromatization (sub-electronvolt up to the megaelectronvolt range) Pulsed light emission (pulse durations at or below one nanosecond, or a billionth of a second).

  • found
  • The modulation of local amide vibrational energies by the longitudinal chain coordinates is found to have a pronounced effect on the broadening of absorption lines. (ebscohost.com)
  • Circular Rydberg states, where the outermost electron is found in a planar circular orbit, are the most long-lived, with lifetimes of up to several hours, and are the most common. (wikipedia.org)
