The electrical properties of some solid organic esters

Because of continued interest in a chemical interpretation of electrical properties the technique of dielectric spectroscopy has been used to determine the molecular configurations of a series of symmetrical diesters of dibasic acids. From a study of the change in the dielectric constants and loss factors brought about by systematic changes in the number of carbon atoms in both the original alcohol and the dibasic acid the possible range of these values has been established. These esters are all white solids and considerable variation in both the physical and electrical properties is observed. From consideration of these characteristics the arrangement of the molecules within the crystalline lattice and the freedom to rotate with changes in temperature and frequency have been established.
