Ion translational energy spectrometry has been applied to study collision induced excitation/de-excitation and dissociation of positively charged ions of the radical SF(q+) for q = 1, 2 and 3. Doubly and triply charged molecular ions are found to be metastable, with the lower limit of their lifetimes against dissociation being almost-equal-to 1-mu-s. Ab initio molecular orbital calculations of the potential energy curves of the ground and low-lying excited electronic states of neutral SF and SF(q+) ions have been calculated using quantumchemical methods in which configuration interaction effects are accounted for by perturbative techniques and via the coupled cluster approach.
