Li. Trakhtenberg et al., The role played by promoting modes and reorganization of reagents in tunneling of H atoms in the fluorene-acridine system, RUSS J PH C, 75(6), 2001, pp. 875-880
Potential energy surface profiles were calculated for hydrogen atom transfe
r in the fluorene-acridine system. It was shown that there existed an optim
al configuration of the reagents at which the potential barrier to chemical
reactions was minimum. The corresponding reorganization of the reagents wa
s calculated. The influence of various promoting vibrations (translational,
librational, and intramolecular) on the rate constant and its temperature
dependence was analyzed.
