That the dielectric constant of a substance is one of its important properties is a fact that has been very commonly taken into consideration by electrical engineers in design of apparatus and transmission lines. The importance of the dielectric constant is equally evident to the chemist working in the field of nonaqueous solutions, and Walden and others have spent a great deal of time and energy in attempting to measure the relationship of the dielectric constant of a solvent to its solvent ability, the degree of ionization of a solute dissolved in it, etc. Indeed it has become very common in chemistry to consider the dielectric constant as one of the fundamental properties of a substance.

The reason for the large influence of dielectric constant is perhaps not evident at first sight. Dielectric constant may be considered as a measure of the electrical energy that can be stored in unit volume of the substance when placed in an electric field. Since energy can be considered to be the product of force times distance, we immediately look for some possibility or an electric displacement within the substance.
