Abstract
The electron impact ionization of some mono- and dinitropyridylphenyls ulfiede, ether, amine and sulfone derivatives were studied at 70 eV en ergy. All the 8 compounds studied underwent ring closure during the fo rmation of a carbazole radical cation as a general feature in their ma ss spectra. The basic differences in the mass spectral behaviour are m ainly attributed to the position of the nitro group in the pyridyl rin g and the fragmentation pathway is directed by the sulfur, oxygen or n itrogen moiety. The base peak in the mass spectra is determined by suc h differences. (C) 1997 by John Wiley & Sons, Ltd.
