The mass spectra of 1,3‐dithiane, 2‐methyl‐ and 2,2‐dimethyl‐1,3‐dithiane have been studied by 2 H labelling and metastable defocusing. The various molecular ions eliminate S 2 H. to produce the ions [C 4 H 7 ] + , [C 5 H 9 ] + and [C 6 H 11 ] + respectively, each of which scramble the hydrogens either before or accompanying further decomposition. Other processes are complex, but parallel those already reported for 2‐aryl‐1,3‐dithianes.
