The mass spectra of mono‐ and di‐substituted alkyl and aryl imidazolines have been measured and the spectra analysed with the aid of deuterium labelling and high resolution techiques. In contrast to the fragmentation of thiazolines, all principal fragments of the imidazoline ring contain one nitrogen with or without hydrogen migration. In the case of 2,4‐disubstituted imidazolines, the presence of two tautomeric molecular ions are suggested.
