pistejoukkotermistön
Pistejoukkotermistön, which translates to "point group terminology" in English, refers to the standardized vocabulary used to describe the symmetry elements of a molecule or crystal. This terminology is crucial in fields like chemistry, crystallography, and solid-state physics for unambiguously classifying and understanding the geometric properties of matter. The system is based on identifying rotation axes, reflection planes, inversion centers, and improper rotation axes.
The primary classifications within pistejoukkotermistön are point groups. Each point group represents a unique set of
Other common notations include Hermann-Mauguin notation, primarily used in crystallography to describe the symmetry of crystals.
