Abstract
The free-energy surface profile for an adiabatic electron transfer reaction in a polar solvent is calculated. The calculation allows for the dependence of electron wavefunctions of reactants on the environment polarization and for nonsphericity of electron wavefunctions. Allowance for the nonsphericity reduces significantly the activation barrier and increases the reaction rate.
