✦ Synopsis

Several [ C,H,OS] + ions with different structures were generated from the appropriate precursors and their metastable ion spectra were determined. Deuterium labelled analogues of some of the I C,H,OS) + ions were used to elucidate the nature of the observed fragmentations and their mechanisms. IC,H,OS] + ions with different C-0-S skeletons were found to give different fragmentation reactions. There are no indications for fast isomerization reactions leading to common intermediates before fragmentation. Most of the observed fragmentations can occur directly from the initial structures.
