Popis:	By means of nanosecond laser flash photolysis it has been found that the interaction between triplet benzophenone (3BP∗) and naphtholate anions (NpO−) is not triplet energy transfer but electron transfer to yield the benzophenone anion (BP−·) and naphthoxy (NpO·) radicals in acetonitrile-H2O (4:1 v/v) at 295 K. From the kinetic parameters for quenching of 3BP∗ by NpO− and quantum yields for the formation of BP−· and NpO·, it was found that the efficiency for electron transfer between 3BP∗ and NpO− is unity due to the triplet spin-multiplicity of radical pairs.
