摘要:应用B3LYP,B3P86方法以及6-311g,6-311g(d,p),6-311++g(df),6-311++g(3df),aug-cc-pvdz,aug-cc-pvtz,D95(d)多种基组,对BS分子,BS+及BS-离子基态进行几何优化和单点能扫描计算.用最小二乘法,拟合得到BSX(X=-1,0,+1)分子(离子)基态的Murrell-Sorbie势能函数.由于BS分子计算结果与实验值符合得很好,首次给出了BSX(X=-1,0,+1)分子(离子)的势能函数,为BSX(X=-1,0,+1)分子(离子)的反应动力学提供了理论依据.
The B3LYP and B3P86 methods have been used to optimize the possible ground-state structures of BS molecule,BS+ and BS-molecule ion with the 6-311g,6-311g(d,p),6-311++g(df),6-311++g(3df),aug-cc-pvdz,aug-cc-pvtz and D95(d) basis sets respectively.Single-point energy scan for BSX(X=-1,0,+1) is calculated.The Murrell-Sorbie function of the BSX(X=-1,0,+1) molecule(ion) ground state is obtained by least square fitting,The calculation results of BS molecule are in good agreement with experimental data.In this work,the potential energy function of the BSX(X=-1,0,+1) molecule(ion) for a ground state is shown for the first time.The work provides a theoretical basis for reaction kinetics.
