Abstract

Symmetry Elements and Operations is a multimedia presentation that illustrates the basics of symmetry with three dimensional molecular models and simple text explanations. Three-dimensional graphics and animations are used to define and characterize the symmetry elements commonly encountered in chemical structures. They include identity (E), inversion center (i), proper rotation axis (C_n), plane of symmetry (sigma), and improper (rotation-reflection) axis (S_n).
