| Abstract: | Measurements of the dielectric constant and the electric conductivity of ice doped with about 10?2N NH4F led to an activation energy of the relaxation time of 0.10 eV=2.4 kcal/Mol. Despite the fact that the relaxation times of pure and doped ice are about the same at temperatures close to ?10°C, the statement ofDengel et al. 1], that NH4F doping does not affect the dielectric relaxation, cannot be maintained in view of the large difference in activation energies. |
