Abstract

The quenching behaviour of triplet benzophenone by N,N-diethylaniline has been directly demonstrated with the laser photolysis method. In acetonitrile solution, ionic dissociation to the benzophenone anion and N,N-diethylaniline cation occurred, while a ketyl radical was formed in benzene solution. Encounter collisional ionic dissociation and hydrogen abstraction compete each other, depending on the solvent polarity.
