Abstract :
An analytical expression for the beat amplitude of recombination luminescence of geminate radical ion pairs in homogeneous solutions is obtained in terms of the step-wise model of the exchange interaction. It is shown that the most effective suppression of the beats amplitude is observed in highly polar media with a weak Coulomb interaction between radical ions. The dephasing effect of a strong exchange interaction in the suppression of the beat amplitude decreases with decreasing polarity of the solvents.
