Recent progress in the studies of anomalous dispersion phenomena

Among the modern methods being used to aid in the correlation of observed chemical and physical behavior of matter with the existing information concerning the structure of molecules the dielectric constant and conductance studies have made possible fuller theoretical and practical understanding of both simple and complex substances. Such added knowledge particularly on the electrical behavior of matter is of special value to the field of electrical insulation not only in the selection and processing of superior insulation material but also in the interpretation of phenomena observed with insulation material now in use under various conditions. Nearly every set of dielectric constant or conductivity data, particularly on insulation material, involves some aspect of anomalous dispersion.
