摘　　要：基团的电子效应与单取代苯对位１Ｈ、１３Ｃ的化学位移＊韩长日冯娇杨钟照平（海南师范学院化学系海口５７１１５８）关键词１Ｈ的化学位移１３Ｃ的化学位移基团电负性共轭效应引言在１Ｈ、１３Ｃ核磁共振谱中，化学位移值的大小主要取决于屏蔽作用的大小，而屏蔽作用的大...The relation ship for the electronic effects (inductive effect and resonance effect) of the groups on the chemical shift of para 1H、para 13 C in monosubstituted benzenes has been investigatal,and a method for calculating the chemical shift of para- 1H、para- 13 C in monosubstituted benzenes has been proposed: δ 1H =1.148R H+0.142X G+6.909 δ 13 C =18.874R H+1.972X G+123.539 The calculated results coincides with the values in literature.
