Abstract

In this study, fully analytical treatment for evaluating the second virial coefficient with Stockmayer potential is presented. This approach is based on the binomial expansion theorems and basic integrals for the analytical representation of the second virial coefficient. The presented relationships for the second virial coefficient over Stockmayer potential can be useful especially in the studies of the interaction of polar molecules with higher dipole moments. The usefulness of the method is confirmed by H₂O, NH₃, and CHCl₃ molecules. The obtained results of second virial coefficient are in good agreement with literature data.

具有Stockmayer势的第二维里系数的完全分析评估及其应用

摘要

在这项研究中，提出了用Stockmayer势评估第二病毒系数的完全分析方法。该方法基于二项式展开定理和基本积分，用于第二维里系数的解析表示。在Stockmayer电位上第二维里系数的关系可以特别有用，特别是在研究极性分子与更高偶极矩相互作用的过程中。H ₂ O，NH ₃和CHCl ₃分子证实了该方法的有效性。第二维里系数的计算结果与文献数据吻合良好。
