## Abstract Molecular orbital calculations using the semi‐empirical CNDO/2 method were carried out on the molecular ion of 3‐__p__‐NH~2~‐phenyl‐5‐phenyl‐1,2,4‐oxadiazole, whose structure had been determined by X‐ray diffraction. The calculated diatomic interaction energy values are consistent with

The fragmentation behaviour of 3,4-disubstituted 1,2,4-oxadiazole-5(4H)-thiones under electron impact (EI) can be explained by postulating a predominant rearrangement to the corresponding 3,4-disubstituted 1,2,4-thiadiazole-5(4H)-ones before further fragmentation. This postulate is confirmed by a co
