This paper reviews data (taken in our laboratory) of complex permittivities of solutions of lithium salts at U.H.F. and microwave frequencies. The solvents used were tetrahydrofuran, dimethyl- and diethylcar-bonate.

Parametric fitting of the data to the sum of a Debye relaxation for the solvent, and to a Cole-Davidson distribution (LiClO4, NaClO4 in THF) and to a Debye function (other systems) for the solute, is reported. The solute relaxation is interpreted as due to rotational relaxation of the dipolar species present in solution. Structural information from IR-Raman spectra and electrical conductance data from the literature are used to substantiate the above interpretation.
