The fragmentation behaviour of ten 3,4-disubstituted 1,2,4-oxadiazole-5(4H)-thiones and seven 3,4-disubstituted 1,2,4-thiadiazole-5(4H)-ones studied here confirmed the earlier observations about the partial rearrangement of the former after ionization into the latter before further fragmentation.

## Abstract The 70 eV mass spectra of a number of derivatives of 3,5โdiphenulโ1,2,4โoxadiazole substituted either in the 5โphenyl (fifteen) or in the 3โphenyl (four) position, have been studied using exact mass measurements and metastable determinations by the defocusing technique. The substituent
