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 dissociation spectra were used to support the proposed ion structures of major fragment ions.
