WebBASIS (or MOTIF): An atom or a group of atoms associated with each lattice point in crystal. CRYSTAL=LATTICE+BASIS LATTICE of a crystal tells how to repeat (the periodicity of the crystal). BASIS tells what to repeat according to the lattice to get the crystal. LATTICE TRANSLATION: A vector from one lattice point to another.

WebJan 25, 2024 · Crystal Lattice or Space lattice is an arrangement of points regularly repeating in space. As it is a repeating arrangement, to describe the space lattice well, we can choose a small part of the lattice, which produces the complete space lattice when repeated in different directions. This small portion of the lattice is called the ‘unit cell.’ WebA crystal system is a set of point groups in which the point groups themselves and their corresponding space groups are assigned to a lattice system. Of the 32 point groups that …
