Electron impact induced fragmentation of the title compounds obeys a route where the lactam moiety, OCNH, is cleaved first, with the accompanying formation of a cycloalkene ion.This can be verified by low-resolution, high-resolution, B/E and B2/E spectra as well as by collisional activation spectra of, for example, the ions m/z 82 and 67 from 7-azaabicyclo<4.2.0>octan-8-one and from cyclohexene.The only, and fairly weak, fragment ions including O and N are
