Abstract
The HO . fragment eliminated on electron impact (EI) from the molecular ions of o-nitrodiarylamines contains either the amine or the aryl hydrogen. Moreover, 2-phenylamino-3-nitropyridine loses H . from the phenyl group. As confirmed by collision-activated dissociation mass-analysed ion kinetic energy spectra, the fragmentation of such compounds involves the formation of carbazole radical cations. Such a process was not observed for the corresponding o-aminodiarylamines
