Abstract
In this paper we report the results of model calculations on the temperature dependence of the electron transfer (ET) rate from cytochrome C to the reaction center in the photosynthetic bacterium chromatium. The effects of both polar medium phonons and of molecular vibrations of the electron donor and the acceptor center were incorporated within the framework of a nonadiabatic multiphonon description of the ET process. The nuclear parameters required to account for the temperature dependence are in accord with the available physical and chemical information regarding this system, while the large electronic coupling indicates the possible role of intermediate states in the ET process.
