Outer-sphere electron transfer in polar solvents
摘要:
The theory of outer-sphere electron transfer reactions in polar solvents is developed. It is based on a description of the solvent by complex dielectric permittivity in the Debye approach. It was shown that the pre-exponential factor of the electron transfer probability in the case of a strong interaction differs from all known pre-exponential factors of earlier works. An activation energy for electron transfer is obtained larger than the well-known expression first obtained by Marcus [1]. A new criterion distinguishing between non-adiabatic and adiabatic reactions is developed. Outer-sphere electron transfer was treated by generalizing and solving the Landau-Zener problem for the case where the system passes the intersection point of electronic terms without velocity and motion in the crossing region is diffusive.
