Influence of a periodic field on the distant electron transfer in biological systems

Abstract

Generalization of the Marcus transfer rate is derived for the case of a dissipative long-range donor–acceptor electron transfer (ET) mediated by specific bridging electron pathways in biological systems and driven by ac-electric field. High-frequency electric field is shown to block and even to invert the transfer if a specific relation between amplitude and frequency of the ac-field is fulfilled.
