Other studies of the time-dependent recombination probability

4 OTHER STUDIES OF THE TIME-DEPENDENT RECOMBINATION PROBABILITY 

D = (1.8 0.6) x 10 12m2s 1. The encounter distance was estimated to be 1.32 nm, which, when used in the Stokes—Einstein relation for the mutual diffusion coefficient, eqn. (28), givesD as (1.1 0.03) x 10 I2m2 s-1, in reasonable agreement with the estimate from fitting experimental and theoretical decay curves (mentioned above). The germinate pair recombination probability at long times was measured and its increase correlates moderately well with T1/2/rj as noted for other systems (see Sect. 3.1) but was concave upwards (see ref. 22). 

There have been surprisingly few studies of the time-dependent recombination probability of radicals in solution. The only one, other than those already mentioned or involving magnetic field effects (see Sect.
