The isomeric 2, 3-, 5, 6-and 8-quinolinylphthalimides give rise to different electron impact ionization mass spectra, which permit easy distinction. The specific fragmentation processes are rationalized in terms of proximity effects and stabilization of cyclic ion structures. Collision-induced disso

Stereoisomeric cisand trans-1-butyl-3-dimethylaminocyclohexanols have been previously reported to exhibit different electron impact (EI) mass spectra. The m/z 100 ion is obtained only from the cis-isomer. The [ C 6 H 14 N ] results of a collision-induced dissociation study are inconsistent with the
The 70 eV electron ionization mass spectra of uracil-fused tetrathiafulvalenes have been studied by accurate mass measurement, metastable ion analysis and collision-induced dissociation. Changes in the structure of substituents, both in the tetrathiafulvalene moiety and on the N1 atom of uracil, cau
