## Abstract The mass spectra of some doubly unsaturated carboxylic acids are reported. Where Cβ2 is quaternary, the fragmentation pathway is similar to that previously demonstrated for Ξ²Ξ³βunsaturated acids. The unbranched acids show different behaviour, similar to their thermal pyrolysis.

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
