with incident light of 405 and 365 nm were studied quantitatively in matrices of 6M LiCl, 4M CH3COONa, and C2H5OH. the radical-anions were shown to undergo reaction of S–S and S–H bond dissociation. Relative efficiency of the observed processes depends on the energy of incident light, on the nature of matrix, and on the degree of self-association of hydrogen sulphide.

Abstract  

Photochemical reactions of disulphide radical anions CH3SSCH 3 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.
