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.
