Abstract:The fragmentation of 4-styrylquinoline (I), 4-(p-nitrostyryl)-quinoline (II), 4-(p-chlorostyryl)-quinoline (III), 4-(p-hydroxystyryl)-quinoline (IV), 4-(p-methoxystyryl)-quinoline (V), 4-(p-dimethylaminostyryl)-quinoline (VI) and 4-(p-cyanostyryl)-quinoline (VII) under electron-impact in the mass spectrometer is reported. The role and the influence of substituents on the fragmentation scheme is discussed. The loss of the substituents from the molecular ion is correlated with LCAOMO quantities.
