Dielectric Loss and Dielectric Constant Measurements in Supercooled Liquids

Abstract

In order to provide further evidence in support of the structural change which takes place in a liquid when it is supercooled, measurements of dielectric loss at high frequencies and of dielectric constant have been made on various polar liquids. The evidence from the dielectric loss measurements is inconclusive but for the four liquids tested a significant discontinuity in the dielectric constant-temperature curve has been established at the melting point in each case.
