Ionic crystals, molecular crystals and atomic crystalsI. key and difficult pointsA key:1. Concepts of ionic crystals, molecular crystals, and atomic crystalsIonic crystal: a crystal made by bination of anions and cations by means of ionic bonds.Molecular crystal: a crystal in which molecules ...
Electronic spectra of molecules and ions in crystals : part 1; molecular crystals, part 2; spectra of ions in crystals This chapter discusses electronic spectra of molecules and ions in crystals. Radiative transitions involving quanta having energies of the order of volts are referred to as ...
Concepts of ionic crystals, molecular crystals, and atomic crystalsIonic crystal: a crystal made by the combination of anions and cations by means of ionic bonds.Molecular crystal: a crystal in which molecules are combined by intermolecular forcesAtomic crystal: a crystal formed by covalent bonds ...
Two bulklike dielectric modes due to the rotation of molecules around short axes and the librational motion were observed in filled 5CB. We found that the properties of 5CB are considerably affected by the filling. A low frequency relaxation process and dispersion of dielectric permittivity due ...
Anisotropy is most easily observed in single crystals of solid elements or compounds, in which atoms, ions, or molecules are arranged in regular lattices. In contrast, the random distribution of particles in liquids, and especially in gases, causes them rarely, if ever, to be anisotropic. A ...
The liquid crystal structures are divided into two main groups: nematic phases with parallel ordering of the long molecular axes and smectic phases having additional layered structure. An interesting phenomenon is that the liquid crystal phases when formed by optical active molecules develop chiral ...
There has been an explosion of interest in the study of molecular crystals, and their applications in optics and electronics. This advanced 1994 textbook describes their chemical and physical structure, their optical and electronic properties and the reactions between neighbouring molecules in crystals. ...
Model kits for any of our models can be supplied on request. Because it is largely impractical to send our large models and giant models out as fully constructed molecules or crystals, we routinely supply these models as kits, albeit kits made specifically for the construction of a particular ...
It describes crystal defects more fully in terms of their nature and their potential physical and chemical consequences. Structural imperfections can be classified into three general types based on their geometry: point, line, and planar. The constraint imposed upon organic molecules as a result of ...
