Solvent Effects on Simple Electron Transfer Reactions. A Comparison of Results in Debye and Non Debye Solvents
Abstract
Estimation of the longitudinal relaxation time for non-Debye solvents is considered on the basis of Hynes' theory for solvents exhibiting more than one relaxation process. It is shown that the major portion of the solvent effect on electron transfer kinetics in these solvents follows that in Debye solvents when the high frequency limiting value is used. The solvent effect on the outer sphere contribution to the Gibbs energy of activation is then examined with respect to the variation in solvent permittivity. Analysis of the available data suggests that the reactants involved in electron transfer are solvated mainly by solvent monomers such that the dielectric constant in the vicinity of the reactant is considerably reduced in protic solvents.
