论文摘要
遵循第一个原则，为分子clf的基态$ x^1σ^+$的分析性出现曲线（BO）的电势曲线提出了[0，\ infty）$的整个范围内核距离$ r \ r \。它基于在小距离距离$ r $和大距离$ r $的多极扩展下匹配扰动理论，它具有两点胶的形式，并提供了3-4个图3-4个数字。它支持具有最大振动号码的5719旋转状态$ν_{max} = 47 $和最大角动量$ l_ {max} = 210 $，其中包括36个弱结合的状态，接近阈值（与阈值限制），具有unergies $ \ sillsim $ \ sillsim 10^{-4} $ hartree。 Van der waals常数$ c^{（clf）} _ 6 \ \ sim \ 29.3 $ a.u.被预测。
Following the first principles the analytic Born-Oppenheimer (BO) potential curve for the ground state $X^1Σ^+$ of the molecule ClF is proposed for whole range of internuclear distances $R \in [0,\infty)$. It is based on matching the perturbation theory at small internuclear distances $R$ and multipole expansion at large distances $R$, it has the form of two-point Pade approximant and provides 3-4 figures in rovibrational energies. It supports 5719 rovibrational states with maximal vibrational number $ν_{max} = 47$ and maximal angular momentum $L_{max} = 210$ including 36 weakly-bound states close to threshold (to dissociation limit) with the energies $\lesssim 10^{-4}$ Hartree. The van der Waals constant $C^{(ClF)}_6\ \sim\ 29.3$ a.u. is predicted.
