The kinetics of the photoreduction of acridine guest molecules in fluorene single crystals has been investigated theoretically. The abstraction has been modeled using the golden-rule approach and proceeds by vibrationally assisted tunneling. Parameter values have been taken from experimental data and from semiempirical force-field calculations. The calculated temperature and isotope effects are in good agreement with the experimental data for acridine and phenazine guests [B. Prass, J. P. Colpa, and D. Stehlik, J. Chem. Phys. 88, 191 (1988)]. While a fluorene lattice vibration is the likely promoting mode, NH wagging in the radical-pair product plays an essential role. [ABSTRACT FROM AUTHOR] |
