研究二面体点群的分子对称性有两个主要困难。一个是确定C2轴垂直于Cn轴的位置，另一个是找到穿过Cn轴并平分相邻C2轴所形成的角的σd平面。本文提出了一种学习绘制二维投影的方法来识别对称元素。并比较了具有相似投影多边形的分子在点群上的差异。
There are two main difficulties in studying molecular symmetry of dihedral point groups. One is locating the C2 axes perpendicular to the Cn axis, while the other is finding the σd planes which pass through the Cn axis and bisect the angles formed by adjacent C2 axes. In this paper, a method of learning to draw 2D projections has been proposed to identify symmetry elements. Molecules with similar projective polygons are also compared to discuss the differences in point groups.
