The interaction of semiquinone and stable nitroxyl radicals has been studied in modeling radiosensitization processes. Bimolecular radical reactions which proceed through one-electron transfer are of interest for the information which they furnish concerning radical reactions, in general, and charge-transfer processes, in particular. The present work used flash photolysis to study the kinetics of electron transfer between semiquinone (Q/sup -//sup ./, QH/sup ./), nitroxyl, and triphenylverdazyl radicals in aqueous and aqueous organic solution.
