Dielectric relaxation of fluoroform gas at 30 megahertz Tsoi, Hoi-Lum
Abstract
Dielectric relaxation of Fluoroform (CHF₋₃) is measured carefully in the density region (0.0009-0.28 amagat) where the molecular reorientational frequency is of the same order as the oscillating electric field of 30 MHz. The simple Debye model, which assumes that the dipole relaxes exponentially towards its equilibrium value characterized by a single relaxation time, is found to be inadequate to explain the experimental data. The Cole-Cole model, which assumes a distribution of relaxation times is tried. Agreement with experiment is only improved at densities below 0.03 amagat.
