High Frequency Dispersion in n-Propanol

Abstract

Two dispersion regions in the liquid in addition to the primary dispersion have been measured at audio‐and radiofrequencies below −120°C, which make small but significant contributions to the dielectric constant. Both move rapidly to lower frequencies with decreasing temperature and the relaxation times of the intermediate dispersion are 200 times smaller than for the primary one. The temperature and frequency dependences are those to be expected for orientation rather than induced polarization.
