Abstract
Admittance data for the liquids Ca(NO3)2·4H2O and Na2S2O3·5H2O at temperatures in the vicinity of Tg are reported. The imaginary part of the dielectric modulus is found to be well described, as a function of frequency, by the Davidson-Cole relaxation function. Average conductivity relaxation times as a function of temperature are found to indicate a varying degree of return to Arrhenius behavior in the two liquids. Na2S2O3·5H2O also shows a distinct secondary relaxation at low temperatures probably associated with the anion or anion bound water molecules.
