title: In the electron impact mass spectra of N,N'-diaryl-1, 3-phenylenediamines, recorded under conditions generating the molecular ion as a base peak, the most important step involve a beta-aromatic cleavage with H rearrangement, leading to the expulsion of a neutral arylamine; this fact can be used in meta isomer identification since for the corresponding 1,2- and 1, 4-isomers the expulsion of an aryl radical is a competitive process
