Abstract:

A method for separating the solvent dependence of the pre-exponential factor from that in the free energy of activation is described for adiabatic electron transfer reactions in which the inner sphere contribution to the activation energy is much less than the outer sphere contribution. The analysis is applied to data published in the literature in which the heterogeneous electron transfer rate constant was measured in at least 4 different solvents. The resulting kinetic parameters are discussed with respect to current theory.
