The methane and isobutane chemical ionization mass spectra of alicyclic substituted 2‐aryl‐1,3‐dithianes were examined by gas chromatography mass spectrometry. The protonated molecular ion was found to be of low abundance in the methane spectra, while a protonated cyclic sulfide cation ( m / z 107) appeared as the base peak. A protonated molecular ion was the base peak when isobutane was used as the reagent gas. Electron impact mass spectra displayed weak molecular ions and were characterized by the m / z 106 fragment.
