Point Groups

Point groups are classifications used in chemistry and physics to describe the symmetrical properties of molecules. They identify the types of symmetry a molecule has—such as rotations, reflections, or inversions—that leave its shape looking unchanged. For example, a molecule with a mirror plane has a symmetry that reflects one side onto the other. These groups help scientists understand molecular behavior, reactivity, and how molecules interact with light. Essentially, point groups categorize molecules based on their symmetry features, providing a systematic way to analyze their structure.
