High resolution mass spectrometry. Part VII. 1,2,3-Thiadiazole derivatives

Abstract

The mass spectra of a number of mono- and di-substituted 1,2,3-thiadiazoles have been studied. The elimination of a molecule of nitrogen from the molecular ion usually occurs prior to fragmentations involving substituents. Some of the compounds yielded M+ 1 ions rather than molecular ions under normal source conditions.
