Dielectric Properties

Part of the Water book series (WCT, volume 2)


The study of the dielectric properties of aqueous solutions of nonelectrolytes includes both the static or low-frequency dielectric constant and the relaxation spectrum or variation of the dielectric constant as the frequency is varied. Since the most important nonelectrolytes are organic liquids, the dielectric properties of these pure liquids must also be studied and understood, as well as those of pure water, which were discussed in Volume 1 Chapter 7 of this treatise. The dielectric properties are to some extent structure-sensitive, that is, they depend upon the correlation or interaction between the electric dipoles, both permanent and induced, principally the permanent dipole moments associated with OH and similar groups. The strongest electric fields acting on the water dipoles are those produced in the neighborhood of electrolytic ions. These will be considered in Volume 3, Chapter 8, except insofar as it will be necessary to consider their relevance to nonelectrolyte solutions.
