(1)討論了用自洽勢場多中心分子軌道法來處理H2分子的一般方法。(2)用僅含兩個參變數三中心分子軌道進行了具體計算,求得H2分子的結合能為3.598eV,接近於Coulson用五個參變數的雙中心分子軌道所得的結果(3.603eV)。(3)用不在原子核上的兩中心的分子軌道求得H2分子的結合能為3.630eV,此上述結果為好。並指出如用不同的α值和四個或四個以上中心的分子軌道,很有可能得到更好的結果。以上處理方法有可能推廣到比H2更為複雜的分子。

Although James and Coolidge (1933) solved the molecular hydrogen problem in almost complete agreement with experiment by using. a 13-term 2-electron eigenfunction, his method can hardly be applied to more complex molecules. For this and other reasons (Coulson, 1938), it is still desirable to obtain a good one-electron eigenfunction, i.e., molecular orbital, for the hydrogen molecule.
