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.
