Abstract: In this paper, the effects of substituents on the infrared spectra of some 1,4-bis[β-(4-substituted phenyl) ethenyl] benzene compounds have been discussed.It was found that there is a relationship of homologous linearity between the out-of-plane C-Hbending vibration frequency of olefinic bond and the substituent constants σp σpo, or, σp+.
