摘要: 取代基对红外光谱特征频率的影响曾有报导,但对1,4-双[β-(取代苯基)乙烯基]苯类化合物还未曾研究。我们测试了它们的红外光谱,发现取代基常数σp、σpo及σp+与反式烯键上碳—氢键的面外变角振动频率δ=C-H(面外)之间存在一定线性关系。

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+.
