Dielectric dispersion in pure polar liquids at very high radio frequencies - III.The effect of electrolytes in solution

Abstract

A description is given of measurements at millimetre and centimetre wave-lengths of absorption in electrolytic solutions, up to concentrations of about 3 normal, with water and methyl alcohol as solvents. The observations are analyzed in terms of Debye’s basic theory of dispersion in a polar dielectric, and it is shown what modifications to the theory are necessary to take account of the ionic conductivity produced by an electrolyte. Measure­ments on aqueous solutions of sodium chloride are discussed in relation to Hückel’s theory of electrolytic solutions.
