Abstract:
The results of studies on the kinetics and mechanisms of reactions involving the transfer of an electron and a hydrogen atom to quinone molecules in triplet states are surveyed and the spectroscopic-kinetic characteristics of the triplet exciplexes of quinones and the role of the electron donor–acceptor interactions and hydrogen-bonded complexes in the photochemistry of quinonoid compounds are examined. Attention is concentrated on the experimental investigation of the kinetics and mechanisms of the primary photochemical processes by modern flash photolysis methods. The bibliography includes 276 references.
