4-Acyl-1,3,4-oxadiazolines were characterized by their mass spectra and retention indexes. It was shown that the spectra of ionic series of compounds of a given class in conjunction with homologous increments of the retention indexes make it possible to carry out their group identification, in particular, to distinguish acyloxadiazolines from the isomeric diacyl- and isobaric monoacylhydrazones, which have similar regularities in electron-impact fragmentation, and that the complete analysis of their mass spectra makes it possible to unambiguously establish the position and character of the hydrocarbon radicals in the molecules.
