长程分子振动光谱的高精度计算

High-precision evaluation of the Vibrational spectra of long-range molecules

C. Tannous, J. Langlois

摘要:

用正则函数法精确地和任意精度地测定了长程分子的振动光谱。$^{23}{\rm Na}_2$分子的$0^-_g$和$1_u$电子态的能级从基态到连续极限确定。通过与Stwalley等人使用相同势和Trost等人基于适用于长程分子的Lennard-Jones势的工作所获得的先前结果进行比较,验证了该方法。

英文摘要:

Vibrational spectra of long-range molecules are determined accurately and to arbitrary accuracy with the Canonical Function Method. The energy levels of the $0^-_g$ and $1_u$ electronic states of the $^{23}{\rm Na}_2$ molecule are determined from the Ground state up to the continuum limit. The method is validated by comparison with previous results obtained by Stwalley et al. using the same potential and Trost et al. whose work is based on the Lennard-Jones potential adapted to long-range molecules.
