Review of current studies in the field of dispersion phenomena

The importance of the relation of physical and chemical behavior to the molecular structure of simple and complex substances is becoming more fully recognized in the solution of theoretical and practical problems arising in academic and industrial laboratories. The knowledge of this relation is of special value to the field of electrical insulation in which the selection and use of materials possessing the proper resistance to electrical end mechanical stresses are subject to more exacting specifications than were previously required. The physicist and chemist have devised and developed a number of sensitive methods for obtaining such structural information. Among these methods are the dielectric and conductivity studies which have materially aided in the search for information concerning the structure and properties of various substances. This is attested by numerous and varied researches reported in the literature during the past year.
