โฆ Synopsis
Dielectric constants
and losses have been measured at eight microwave frequencies between 1 and 35 GHz for 1-butanol and 1-decanol in paraffin oil and paraffin oil-n-heptane mixtures at 25 "C. The data have been analyzed in terms of two relaxation times and their dependence on viscosity and concentration is examined. The dielectric relaxation behaviour of these alcohols is not affected to any appreciable extent by increased macroscopic viscosity.
