摘  要:文章采用多参考组态相互作用方法(MRCI)计算了HgCl分子低激发态12Π、B(2)2Σ+和22Π的垂直激发能,并利用LEVEL程序求解了束缚态X2Σ+、B(2)2Σ+和22Π的振动能级,为后续实验提供理论参考。

Abstract: In this paper, the vertical excitation energies of the low-lying excited states 12Π, B(2)2Σ+ and 22Πof HgCl molecule are determined by making use of the multi-reference configuration interaction method(MRCI). The vibration levels of the bound states X2Σ+, B(2)2Σ+ and 22Πare calculated by using the LEVEL program, which provides theoretical reference for follow-up experiments.
