本文提出了电子亲合力与诱导效应之间的定量关系。通过计算说明了电子亲合力与诱导效应的定量相关比电负性与诱导效应的定量相关好得多；并应用其定量关系式预测尚未实测到的取代基的电子亲合力值；根据计算结果, 可从不同实验方法测得的电子亲合力值中选择正确的实验值。该定量关系式能更加准确和定量地表征出诱导效应的作用。

关键词: 电负性, 诱导效应, 电子亲合力, 定量关系

This paper proposed the quantitative relationship between electron affinity and induced effect. The relative computation shows that the relativity between electron affinity and induced effect is much better than that between electronegativity and induced effect. Its equation can predict the unmeasured values of electron affinity of substituting groups. According to these computated results, the correct experiment values of electron affinity can be chosen from the values of electron affinity which are measured by various experimental methods. The equation illustrates the effects of induced effect quantitatively and more accurately.

Key words: INDUCTIVE EFFECT, ELECTRONEGATIVITY
