As they have a relatively low ionization potential, aromatic amines in a condensed phase usually participate in the electron phototransfer reactions, but together with this reaction, a photodissociation of the N-H bond may also take place. At the present time, the photodissociation of the C-H bond in the hydrocarbon molecules has been fairly well studied, and it has been shown that with regard to the predissociation mechanism, this process may proceed via triplet states. Dissociation by a nonadiabatic mechanism is possible in singlet states, but for the molecules its probability is usually small. The presence of an unshared pair of electrons on the nitrogen atom (the Z-electrons) in the molecule of an aromatic amine may appreciably change the mechanism of the photodissociation of the N-H bond. The study of this problem is the aim of this investigation.
