Abstract: | The mass spectral fragmentation patterns of thirteen 2′,3′ and 4′-R-trans-2,4-dinitrostilbenes obtained by electron impact have been studied. The main routes of fragmentation involves loss from the molecular ion due to the ortho effects of the 2-nitro substituents. Substitution on positions 2′,3′ and 4′ of stilbene moiety does not influence the fragmentation patterns. |
