Flash photolysis study of phenyl-substituted phenols, quinones, and corresponding free radicals. Part 3. Intermediates in the photolysis of phenyl-substituted phenols

Abstract

Aryloxyl radicals are formed on photoexcitation of phenyl-substituted phenols in a biphotonic process involving the triplet excited state. These aryloxyl radicals are also formed on photolysis of the corresponding phenolate ions in the presence of oxygen involving the singlet excited state.
