Dielectric Properties of Substances

Electric and magnetic interactions play an enormous role in chemistry and chemical technology they govern the processes taking place in atoms and molecules, crystals, electrolysis, surfaces of solids electrolyzing of dielectric polymer materials and others. Because the electric field in molecular systems has a very complex structure, for the convenience of the reader, we will give the nomenclature of electric fields at the beginning of the chapter. 

Let us start by briefly presenting the main information on electric charges and the characteristics of the fields they create.

Some considerable knowledge about the electrical make-up of molecules is, however, derivable from the study, on the one hand, of the dielectric properties of substances, and, on the other hand, of band spectra. The former study yields information about the charge distribution between the atoms, and incidentally many interesting facts relating to molecular structure generally. The latter reveals the kinds of electronic transition which occur in molecules and also provides a method for the determination of various important molecular constants.
