Photochemistry of disulphide radical anions in the solid phase

Photochemical reactions of disulphide radical anions RSSR (R = H, CH"3, C"2H"5) i glassy matrices at low temperatures have been studied. It has been shown that upon excitation disulphide radical anions may enter into electron photodetachment reaction and SS and SR bond cleavage. Nonem...

Photochemical reactions of disulphide radical anions RSSR (R = H, CH"3, C"2H"5) i glassy matrices at low temperatures have been studied. It has been shown that upon excitation disulphide radical anions may enter into electron photodetachment reaction and SS and SR bond cleavage. Nonempirical calculation of the H"2S"2 radical anion electronically excited states has shown that dissociation along the SS bond originates from the unbound 1 ^2A state, while dissociation along the SH bond can result from non-adiabatic transitions from the first excited states. The kinetic non-equivalence of disulphide radical anions in photochemical reactions is manifested in the different mechanisms of their transformations. Ausführliche Beschreibung
