Abstract
Negative ion formation by electron impact has been studied in hydrogen sulphide, methylmercaptan, phenylmercaptan, benzylmercaptan, allylmercaptan, dimethylthioether, dimethyldisulphide and diallyldisulpbide. Appearance potentials, ionization efficiency curves and the kinetic energies of negative ions were measured by using a Fox ion source. The energies of various dissociative electron capture processses are discussed and electron affinities of some radicals of the types RS and RS2 are derived. Two chemical reactions of the CH2S- ion with dimethyldisulphide have been detected.Keywords
