摘要：

The energy gap dependence of back electron transfer in contact ion pairs, which is not explained by the Marcus theory, has been explained successfully over the whole range of energy gap, by invoking a mechanism based on an interplay between solvent relaxation and electron transfer. It is concluded that in the normal region (-DELTAG < lambda) back electron transfer occurs in the course of solvent relaxation to the equilibrium state, while in the inverted region (-DELTAG > lambda) it occurs after the equilibrium state is established.
