• The mass spectra of 3-phenyl- (I), 3-tolyl- (II), 3-chlorophenyl- (III), and 3-trichlorophenyl- (IV), -5-chloromethyl-1,2,3-oxathiazolidine-2-oxides have been obtained. The major path in the electron impact-induced cleavage of all the compounds involves the loss of SO<SUB>2</SUB> and Cl from each molecular ion (M). The M–SO<SUB>2</SUB>–Cl ions show the loss of CH=CH<SUB>2</SUB>, followed by the loss of the hydrogen radical and HCN. On the other hand, in compounds II, III, and IV, the M–SO<SUB>2</SUB>–Cl ions show the loss of the ring-substituted methyl or chloro radical. The above fragmentation pathways associated with metastable transitions or the chlorine isotopic clusters for each ion of III or IV have been outlined and discussed for each group of compounds.
