Abstract
An analytical expression for the beat amplitude of the recombination l uminescence 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 bet ween radical ions. The dephasing effect of a strong exchange interacti on in the suppression of the brat amplitude decreases with decreasing polarity of the solvents.
