Chemical3
The first law of photochemistry, known as the Grotthuss-Draper law (for chemists Theodor Grotthuss and John W. Draper), states that light must be absorbed by a chemical substance in order for a photochemical reaction to take place. (wikipedia.org)
According to the second law of photochemistry, known as the Stark-Einstein law (for physicists Johannes Stark and Albert Einstein), for each photon of light absorbed by a chemical system, no more than one molecule is activated for a photochemical reaction, as defined by the quantum yield. (wikipedia.org)
The BGSU team showed that following ultraviolet excitation of geminal tribromides, including bromoform, what looks like simple fission of a carbon-bromine bond at first look is in fact isomerization (the process by which one molecule is transformed into another molecule with exactly the same atoms but in a different arrangement, and with different chemical properties) at fairly large distances via roaming of the molecular fragments. (sciencedaily.com)
Species3
The main transport phenomenon there is "molecular diffusion", which influences the distribution of the species differently according to their molecular mass. (aeronomie.be)
The practical consequence of roaming isomerization of this molecule is that it is thought to be followed by elimination of molecular bromine, leading to an increase of the reactive stock of this species in the atmosphere. (sciencedaily.com)
The aim was to achieve sensitive and accurate temperature and atomic molecular species measurements in situ in reactive flows with high spatial and temporal resolution. (lu.se)
