摘要：

分子点群是结构化学课程中分子对称性章节中的核心内容，是学生深入学习、认识和理解分子结构对称性以及结构与分子性质之间关系的理论基础。其中，分子点群的判别是分子点群的重要知识点之一。本文回顾了国内外不同结构化学教材中分子点群的判别流程，讨论了现有分子点群判别流程在判断分子所属点群中可能出现的问题以及不足之处，并提出了分子点群判别中部分流程的改进方案，有助于学生更加深刻理解分子点群的内涵。

Abstract:

The conception of point group of molecules is one of the core contents in chapter of molecular symmetry of structural chemistry course. It is also one of the basic theories to understand the strucutral symmetry of molecules and the relationship between their structures and molecular properties. Therefore, it is of importance to master the identification method of point group of molecules based on their symmetric elements in structures. This paper compared the identification processes of point group of molecules in different structural chemistry textbooks, discussed potential imperfections of classic identification process of point group of molecules, and proposed a modified identification process of point group of molecules, which could help undergradute and graduate students to know and understand the intention of point group of molecules.

Key words: Structural chemistry, Molecular symmetry, Point group of molecule, Molecular model
