The various modes of fragmentation of 1,4 dithiane and 1,4 oxathiane under electron‐impact have been discussed using variation of their mass spectra with electrons energy, high resolution and AP of the main ions. It is shown that they are qualitatively very similar, but differ considerably from those of 1,4 dioxane.
