Fragmentation of IsomericN-Quinolinylphthalimides on Electron Impact Ionization

Adrian Weisz, Denis Andrzejewski, Asher Mandelbaum

Open publisher page 5 citations

Abstract

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 process 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.
