摘要
本文采用密度泛函理论中的B3LYP方法,以cc-pVDZ为基函数,对MgA l分子的基态势能进行计算,根据计算值拟合出了MgA l分子的势能函数的各参数,并根据拟合出的参数值计算出了力常数和光谱数据.
In the article, the potential energy for the ground state of MgAl molecule is calculated by using the method B3LYP With cc -PVDZ basis set. Supported by the calculated results, the parameters of the MgAl potential energy function are obtained by the least - squares fit. Based on these fitted parameters, the force constants and spectrum data are derived.
