The Solid State and Symmetry

The elements of group theory are outlined, along with applications to vibrational spectroscopy, orbital interactions, and orbital hybridization. The structural properties and common structure types for crystalline solids are given. The radius-ratio method and its problems are discussed. Polymorphs and polytypes are defined. The properties, structures, and bonding of metals and semiconductors are discussed. The structures and special properties of spinels and perovskites are described. The coverage of these topics includes references published through to mid-2021.
