在只考虑弯曲振动与总角动量的耦合,而冻结伸缩振动的模型下,采用Jacobi多项式作为弯曲振动的基函数,用严格的变分法研究了H_2O分子的振转激发态的成簇现象.本文计算了H_2O分子的振转能级和函数,研究了振动激发态下转动高激发态光谱中出现的成簇态.
Considering only the coupling between bending vibration and total angular momentum, the Jacobi polynomial is used as the basis function of flexural vibration in the model of frozen telescopic vibration. The clustering phenomenon of the excited excited states of H 2 O molecules is studied by the strict variational method. In this paper, the vibrational levels and functions of H 2 O molecules have been calculated and the cluster states appearing in the excited high-excited-state spectra have been studied.
