Radio-frequency spectroscopy as applied to problems of dielectric behavior

The new techniques of nuclear magnetic resonance and pure quadrupole magnetic resonance were discussed, particularly in so far as they contribute to the solution of problems of interest in the study of dielectric properties. Results of recent investigations of the motions of molecules and parts of molecules in molecular solids by these methods show that they are often complimentary to the information obtained by dielectric constant studies. The relationship between “relaxation times” obtained in the two fields and the possible need for a reevaluation of dielectric relaxation theories for solids were presented.
