Remote ionization and recombination through the multichannel electron transfer Original Research Article

Vibronic states of the inner mode assisting forward and backward electron transfer are taken into account in calculating position dependent rates of the process in solvents of different polarity. In polar solutions the radius of the remote reaction layer becomes shorter and the maximum rate larger if the highly exothermic electron transfer (in the inverted region) is accompanied by vibronic excitation of the products. The same is valid for the ionization of neutral reactants in non-polar solvents but not for the ion recombination that remains as distant as before although less efficient.
