Crystallography group theory
WebJan 30, 2024 · Symmetry operations and symmetry elements are two basic and important concepts in group theory. When we perform an operation to a molecule, if we cannot tell any difference before and after we do the operation, we call this operation a symmetry operation. This means that the molecule seems unchanged before and after a symmetry … Web12 Evgraph Stepanov Fedorov (1853-1919), and William Barlow (1845-1934) also applied group theory to crystallography, though independently of one another. See Burckhardt (1965), and Lalena (2007 ...
