Title: Possibility of the determination of tunneling parameters from experimental data on photoinduced electron transfer

Abstract

The author proposes a simple method for determining the parameters (a and v) in the expression for the dependence of the tunneling probability (w) on the distance (r) between reactants (w=v exp (-2r/a)) for reactions involving tunneling electron transfer from electronically excited donor molecules to acceptor additions from experimental data on the photogeneration of radical ions. The method presented is based on the study of the dependence of the concentration of the unionized donor particles on the irradiation time. The method has been used to determine the tunneling parameters for photoinduced electron transfer from zinc and magnesium porphyrins to CCL/sub 4/ in glassy alcoholic matrices at 77 degrees K.
