WebPoint groups are a method of classifying the shapes of molecules according to their symmetry elements. Before we can talk about point groups, we need to describe the basic elements of symmetry. These are the proper axis of symmetry (or just axis of symmetry), improper axis of symmetry, plane of symmetry, and inversion center (or point of symmetry). WebNov 26, 2024 · The title represents my overall question.
