Abstract
The variation with viscosity of the fraction of radicals which survive re-e ncounter within the geminate period of a radical recombination reaction is measured using the relative contributions of the triplet and radical pair m echanisms to the electron spin polarization observed in their electron spin resonance spectra. This fraction differs from the fraction of re-encounter s as a result of reaction. From a triplet precursor 2% of the radicals prod uced in a photolysis flash recombine in the geminate cage in methanol but 1 5% do in propan-1,2-diol.
