The mass spectra of S ‐(1‐aryltetrazol‐5‐yl)‐monothiocarbonic acid esters have been studied. The stability of the ester molecular ions is lower than the stability of the corresponding 1‐aryl‐5‐mercaptotetrazoles. Substituents at the phenyl group increase the stability, whereas the influence of the ester alkyl groups is very small. The esters undergo fragmentation via four different fragmentation pathways. The elimination of carbon dioxide is influenced by an ‘ ortho effect’ of the substituents.
