建立 A—B 键中某价电子的键强参数的概念:f_(1,A-B)=(?)ε_(?)/(?)ι_(A-B)表达价分子轨道 i 上一个电子对 A—B 键中化学结合力的贡献.从理论上说明它是 i-电子云对 A 及 B 核的“拉力”以及对其它电子的“推力”的“净效应”大小.就 CO,N_2,O_2说明其所反映的“成键性质”与 UPS 的实验数据相一致.就几个均匀环状化合物证明其有很好的“加和性”.多中心键的 F_1与其中“双中心”键的 f_1之和相等.其所反映的“成键”性质与 MO 的对称性及电荷密度分布图的定性结论完全一致.f_(▲_B)=(?)所反映的键强度与键长及“键电荷”的大小顺序相适应.
To establish the concept of the bond strength parameter of a certain electron in A-B bond: f_ (1, AB) = (?) Ε_ (?) / (?) Ι_ (AB) Expression of price Molecular orbit i Previous electron pair A-B The contribution of the chemical binding force in the bond theoretically shows that it is the “net effect” of the “pull” of the i-electron cloud on the A and B nuclei and the “thrust” of other electrons. The “bonding properties” reflect the experimental data of the UPS, and several homogeneous cyclic compounds proved to have good “additivity.” F_1 of the multinocular bond and f_1 of the “double centered” bond And the same.The reflection of the “bond” nature and MO symmetry and the charge density distribution of the qualitative conclusions are consistent.f_ (▲ _B) = (?) Reflects the bond strength and bond length and the “key charge” The size of the order to adapt.
