The Pearson symbol is a shorthand notation used in crystallography to describe the structure and symmetry of crystal systems. It combines the information about the crystal's lattice type and the number of molecules per unit cell into a concise symbol.

Quantum crystallography is an advanced field that combines principles of quantum mechanics with crystallography, the study of crystal structures and their properties. It focuses on understanding and describing the arrangement of atoms in crystalline materials at a quantum level. This field leverages quantum mechanics to gain insights into the electronic and structural properties of crystals. Traditional crystallography often uses X-ray diffraction to determine the positions of atoms within a crystal lattice.
