Electron Transfer and Tunneling in Chemical and Biological Systems

Abstract

Various aspects of electron transfer reactions in chemical and biological systems are discussed . They include the role of potential energy surfaces, nuclear tunneling, temperature behavior, thermodynamic factors, relation of the preexponential factor in the rate constant to electron tunneling, the effect of applied electric fields, and charge transfer and other spectra. Classical and quantum equations are given, and the relation between recent and earlier quantum theories is discussed. Several biological reactions are considered with these results in mind, utilizing some information available in chemical systems.
