On the basis of perturbation theory, HMO method is used to calculate d~ configuration stabilization energy (i. e crystal field stable energy, CFSE) which in some cases should be considered in determining molecular structure of coordination compounds.

• 根据微扰理论,用HMO法计算了各种d~n构型的稳定化能(即晶体场稳定化能,CFSE),这是在若干化合物决定构型时须予考虑的另一因素。
