摘要 采用了微机版的Gaussian 94程序以及CIS方法和CIS MP2方法对S2 分子的部分单重激发态和三重激发态进行了研究。计算表明 :CIS方法和CIS MP2方法对S2 分子的低单重激发态基本适用 ,可以给出较为满意的结果。但对S2 分子的三重激发态和高激发态 ,CIS方法还需进一步改进。 Some Singlet and triplet excited states are studied with CIS and CIS-MP2 method with Gaussian 94 Package. It is shown that this technique is easy and quite successful to apply to low singlet states of S 2 molecule. But it needs improvement for calculation for triplet and high excited states.
