Dielectric spectra of some common solvents in the microwave region. Water and lower alcohols

Abstract

Precise complex permittivity spectra of the hydrogen-bonding liqs. water, methanol, ethanol, 1-propanol, and 2-propanol have been detd. in the frequency range 0.95-8. GHz. The dielec. relaxation behavior of water is governed by two exponentials, whereas three discrete dispersion steps are found for the alcs.
