摘要: 本文使用SCF、MCSCF、SOCI方法计算了CH2的基态和三个激发态.讨论了总能量、稳定性、平衡几何构型和振动频率等性质.所得结果与实验和理论计算的文献值相吻合,并且预言了一个新激发态c1∑x+的性质.Abstract: In this paper, the ground state and three excited states of CH2 are calculated by usingSCF, MCSCF and SOCI methods. Some properties such as toeal energy, stability, geometry,vibrational frequencies etc. are discussed. The results are well agreement with other authors andsome properties of the c1∑x+ state are predicted.
