EFFECT OF THE ELECTRIC-FIELD ON THE ELECTRON-TRANSFER PROCESSES IN SYMMETRICAL DIMERIC SYSTEMS

The kinetics of photo-induced charge separation resulting from reversi ble outer-sphere electron transfer processes in symmetrical one-dimens ional dimeric systems, such as bianthryl, perturbed by an external ele ctric field, in liquid solutions are investigated. The theoretical app roach is based on Zusman-type kinetic equations, and applies to adiaba tic and non-adiabatic electron transfer processes. Model calculations demonstrating the response of the steady state decay of the three-surf ace system to the external electric field perturbation as a function o f the dielectric relaxation rate of the solvent, reorganization energy and the free energy are presented.
