A recently introduced method by Deutch for determining the mean passage time for diffusion controlled processes (J. Chem. Phys. 73, 4700 (1980)) has been further developed for application to the reactions of geminate pairs. First, a nonzero probability of escaping geminate recombination requires a normalized definition of mean recombination time which is done consistently. Second, only a finite dose results in a finite mean reaction time. Adopting a special outer boundary condition related to the dose, mean recombination times are calculated for ionic and neutral geminate reactions. For application in radiation- and photochemistry, fully and partially diffusion controlled conditions are applied to ionic and neutral cases, respectively.
