Abstract

Admittance data for the liquids Ca(NO₃)₂·4H₂O and Na₂S₂O₃·5H₂O at temperatures in the vicinity of T_g 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.
