Mechanisms of Charge Separation and Subsequent Processes Group Report

Abstract

The theoretical aspects of charge separation were discussed in this group and reexamined, in particular with respect to tunneling (cf. Grätzel et al., this volume). Basically three theories approach the general problem of rate reactions and are potentially applicable, among other processes, to electron, proton , or H-atom transfer, as long as these are "one step" processes. The best known treatment and the most widely referred to in the literature (because it is best understood by the experimentalist) is the one elaborated by Marcus (15). This theory is considered classical because the nuclear motions are treated on a classical basis, quantum mechanics being applied to the electron motion.
