Crystallographic symmetry
WebThe book is composed of seven chapters and five appendices; it can be divided into two large sections: one about crystallographic symmetry (chapters 1 to 4), the other about the description of crystal structures in … WebParts 8 to 15 deal with the following aspects of symmetry theory: the mathematical approach to space groups; crystal lattices; point groups and crystal classes; symbols for symmetry operations; symbols for space groups; isomorphic subgroups of space groups; lattice complexes; and normalizers of space groups.

Crystallography is the experimental science of determining the arrangement of atoms in crystalline solids. Crystallography is a fundamental subject in the fields of materials science and solid-state physics (condensed matter physics).
