Photochemical reactions of disulphide radical anions in Frozen water-salt matrix

Photochemical reactions of disulphide radical anions CH₃SSCH₃^– induced by light with =436, 405 and 365 nm in a watersalt matrix of 6M LiCl at 77 K have been studied. It has been shown that upon excitation disulphide radical anions may enter into electron photodetachment reaction and the S–S bond is cleft. Kinetical nonequivalence of disulphide radical anions in photochemical reactions has been shown to manifest itself in different mechanisms of their transformations.
