摘要: 用量子化学从头算方法,计算得到了S3分子优化的几何结构(基态和几个低激发态);研究了其在C2vCs群对称性下的解离过程,给出两种群对称性下基态和激发态的势能曲面及等高投影图;在两种群对称性下均得到在相应势能曲面上的优化的解离路径.

Abstract: Using quantum chemical ab initio method,the optimized geometry structure of S3 molecule in ground state and several low-lying excited states were obtained. In C2v and Cs symmetry,we study the dissociation processes and the PESs(potential energy surface) of the low-lying states. In both symmetries,we all obtained optmized dissociation paths on the corresponding potential energy surface.

Key words: S3, MCSCF, Molecule structure, Dissociation path
