Translational energy spectrometric and quantum chemical study of CS^q+ (q=1, 2) radicals: charge stripping and dissociation

Abstract

A combined experimental and theoretical investigation has been carried out on CS⁺ and CS²⁺ radical ions. Ion translational energy spectrometry has been applied to study charge stripping of CS⁺ ions to yield metastable CS²⁺ ions and to study the energetics of spontaneous and collision-induced dissociation of these metastable doubly charged ions of CS. All-electron ab initio molecular orbital calculations, inclusive of fairly large-scale configuration interaction procedures, have been carried out to compute the potential energy functions of the different ionic systems involved in the collision processes studied experimentally.
