Experimental and Theoretical Studies of Intramolecular and Intermolecular Dynamics

摘要

Significant progress has been made in both experimental and theoretical studies of intramolecular and photochemical processes. The concept of kolmogorov entropy has been extended to the quantum mechanical case and has been used to interpret the nature of chaos in quantum mechanical systems. A detailed study of radiationless processes in cold isolated naphthalene was completed and in which the first evidence for a promoting mode was identified. Striking quantum mechanical effects in very low energy collisions of atoms with polyatomic molecules was discovered. A detailed study of collision induced energy exchange in electronically excited pyrazine was completed and which resulted in the development of a correlation type theory of the rules governing such processes. Finally, a joint theoretical and experimental study of the effect of initial rotational state selection of photophysical and photochemical processes has been completed. (Author)
