โœฆ Synopsis

The model of a photoinduced electron transfer in a donor-acceptor pair including singlet and triplet electron excited states of the donor is presented. Within the framework of a stochastic approach the probability of the transition to the triplet donor state caused by an external magnetic field is found. It is shown that this transition can block the electron transfer from the singlet donor state and, therefore, can essentially change the reaction kinetics. The possibility of extracting direct information on the reaction coordinate dynamics from the dependence of the effect on the magnetic field strength is briefly discussed.

We treat the electric field effect on electron transfer processes. As an application, the effect of electric field on the Marcus-Levich theory is presented. For comparison, the electric field effect on absorption spectra is also discussed.
