A study has been made of the fragmentation upon electron inpact of 3,3-dimethyl-2,3,4,5,10,11-hexahydro-11-phenyl-1H-dibenzodiazepin-1-one and fifteen of its derivatives containing chloro, bromo, methyl, methoxy, hydroxy, nitro, amino, carboxyl, and carboxymethyl substituents on ortho and para positions of the 11-phenyl ring.All the spectra analyzed contain molecular ions and the principal fragmentation routes takes place either from the molecular or from ( M+ -1) ion.There are, however, some deviations from the general fragmentation pattern in the case of 1,4-dibenzodiazepin-1-ones with o-nitro, o-hydroxy and o-carboxyl substituents caused by direct interactions of these groups with the benzodiazepine ring.
