β¦ Synopsis
The free energy change of an electron transfer reaction in a polar solvent is rigorously analyzed within the framework of the dielectric continuum model. An appropriate expression for the electrostatic energy between the two product ions separated by R is derived. The present result does not support a recent claim by Suppan that, if R is close to the contact distance, the electrostatic energy should be much larger in magnitude than estimated from the usual expression -e'/t,R.

## Abstract Chemically induced dynamic nuclear polarization (CIDNP) observed during electron transfer (ET) reactions of tertiary amines such as DABCO (**1**) or Et~3~N (**2**) with a wide range of electron acceptors support the involvement of amine radicalβcations (__e.g.__, **1^.^**^**+**^ or **2^
Recently Kakitani and Mataga claimed that the free energy dependence of electron transfer rates in polar solvents could be explained by taking into account the dielectric saturation effect of polar solvents. It is shown that the basic assumption of their model is incorrect. The correct treatment of
We conducted Monte Carlo simulations of polar solutions by explicitly treating the effect of electronic polarizability of solvent molecules. Based on these data, we calculated the energy-gap dependence of electron-transfer rates. It was found that a considerable asymmetry of the energy-gap dependenc
