The temperature dependence of the rate of electron transfer is analyzed in the framework of a molecular theory presented recently, characterized by decoupling the total solvent reorganization energy into two contributions featuring reorganizations of permanent dipoles as well as solvent density. The
Experimental data for the energy, the oscillator strength and the temperature dependence of the maximum of the allowed spectral transition of ammoniated and hydrated electrons arc shown to bc in good agreement with recent theoretical models.
