Spectral Methods in Transition Metal Complexes || Electronic Spectroscopy
摘要： The electronic spectrum covers the range from 200 to 800 nm of the electromagnetic spectrum: 200–400 nm is the ultraviolet region and 400–800 nm is the visible region. Hence, the electronic spectrum is also known as the UV-Vis spectrum. The major application of this spectrum to metal complexes is the determination of the geometry of the complex. In order to arrive at this application, we must understand Term Symbols ?rst. If we want to understand these concepts, selection rules, and transitions, we must have a clear understanding of the concepts of the symmetry of molecules, the symmetry elements, symmetry operations, point groups of molecules, character tables, direct product concepts, and so on. Hence, we will discuss these concepts before the term symbols.

Fundamentals of Electroceramics (Materials, Devices, and Applications) || Binding Forces in Solids and Essential Elements of Crystallography
摘要： In this chapter, we will study how the solids are held together in a structure that can be either polycrystalline or single crystal, how solids are classified based on their governing binding forces, the relationship between structures and the properties they acquire when subjected to an external agent such as an electric or a magnetic field, and, finally, how these properties help engineers and scientists develop devices and their applications. We will also study the nature and properties of single crystals and how their unique properties help us in understanding their importance to science and technology.
