Resumo

Within the framework of the stochastic approach, a numerical study of the kinetics of occupancy of the triplet state of an electron donor molecule caused by photoinduced electron transfer from the donor to the paramagnetic acceptor and back is performed. The conditions are determined, and a general strategy for achieving the maximum efficiency of triplet molecule accumulation induced by the electron transfer is stated. Solvents with fast dielectric relaxation are shown to contribute to increasing the efficiency of the process involved.
