The dielectric properties of formamide, ethanediol and methanol

Abstract

The dielectric properties of the solvents formamide, ethanediol and methanol have been studied over a frequency range of 10 MHz-70 GHz and a temperature range of 10-40 degrees C. It was found that formamide is best represented by a single Debye type dispersion, ethanediol by a double Debye and methanol by a Cole-Cole distribution of relaxation times.
