The electron impact mass spectra of several gem-bisamides are studied. The dominant peaks in the spectra of alkylidene and arylidene bisalkylamides are formed by the cleavage of the C -N bond of the amido group with charge retention on the nitrogen atom. This fragmentation, followed by the loss of a

The electron impact ionization of some mono-and dinitropyridylphenylsulfiede, ether, amine and sulfone derivatives were studied at 70 eV energy. All the 8 compounds studied underwent ring closure during the formation of a carbazole radical cation as a general feature in their mass spectra. The basic
