摘要
用二参方程ф=Z2ri/Z*2rc计算Lewis酸软硬的标度,参数Z/r2i与静电力有关,Z*/r2c与共价力有关.运用该式计算119种酸的软硬度值,结果与Pearson根据实验总结的分类结果一致.
In this paper, a scale for the Lewis acid strength has been calculated from the dual parameter equation φ=XZ/ri^2 Z^＊/rc^2 One parameter,Z/ri^2, is related to electroslatic force, another parameter, Z^＊/rc^2,is relat-ed to covalent force. By this formula, hardness -softness of 119 acids is calculated. This result is identical with Pearson＇s experiment classification.
