For NaCl we determine them by using κ 0, κ and β (the optical dielectric constant, the static dielectric constant and the compressibility). In this case our quadratic formalism has only three unknown constants, which are determined by using three observed quantities. When the polarizability of the positive ion is much smaller than that of the negative ion, we may be allowed to put p 2 =0. Using this formalism it is possible to derive several important relations concerning the dielectric properties of ionic crystals. The energy change due to the electric field is expressed by a quadratic form of quantities p x, p 1 and p 2, which represent the dipole moments due to the displacement of ions, the deformation of the negative ion and the deformation of the positive ion in the electric field respectively.īlofeld Software Editor Videos. A general theory of the dielectric constant of simple ionic crystals is proposed. The classical theory of the polarization of dielectrics shows that such properties of a molecule are exhibited in the behavior of the substance in an electric field. Those electrical properties of the molecule must be selected that are capable of a theoretical interpretation. Part of the book series (PMOC) Abstract An investigation of the electrical characteristics of a molecule gives important information on the distribution of charges in the molecule and provides the possibility of determining many properties of the molecule which depend on its electronic distribution.0 Comments Performance In a Leading Role.
