## Abstract The relative stabilities, isomerizations and dissociations of ionized dimethyl sulfoxide (DMSO), its three C~2~H~6~OS^+·^ isomers and of all their 14 conceivable CH~3~OS^+^ fragments (1–14), have been investigated by __ab initio__ calculations at the MP2/6–31G(d,p)//6–31G(d,p) + ZPE and
