对反应A+B=AB, 将反应物A+B的波函数生成物AB的组态波函数正交展开, 可以得到AB键形成时σ键和π键所占的比例, 从而提供了一种研究分子间相互作用本质的半定量方法。以BH3+CO=H3BCO反应为例说明了该方法的应用。

The mol. interaction energy orthogonality decomposition method is based on expanding the wave function of combined reactants A and B into a series of selected electronic configuration wave functions of the product AB. A quant. estimate of the relative importance of s and p bond in A-B bond is obtained. As an example, the orthogonality decomposition of the reaction energy of BH3 and CO forming borane carbonyl is carried out to illustrate the application of this method.

Key words: CHEMICAL REACTION, MOLECULAR ORBITAL THEORY, ENERGY DECOMPOSITION METHOD
