Dielectric Relaxation of Alcohol–Heptane Mixtures

Abstract

IT is well known¹ that pure alcohols exhibit a large dielectric absorption at radio frequencies, together with a very much smaller absorption in the centimetre region. For measurements at a fixed wave-length of 10 cm., this corresponds to the occurrence of loss peaks at temperatures of the order of + 100° C. and – 100° C. respectively. In practice, the low-temperature loss peak thus found would be largely obscured by the loss at high temperatures; but this is no longer the case when the alcohol is dissolved in a non-polar solvent.
