The Debye relaxation equation and its derivatives were used to analyze the experimental permittivity data of high purityPropan-1-ol and Propan-2-ol over the frequency up to 10GHz and temperature range of 10ºC to 50ºC. The plots of dielectric constant and loss factor against the frequency were found useful in determining how well experimental data fits the Debye equation and these methods were also found capable of reproducing good results of fitted data using double-Debye. The dielectric constant of Propan-1-ol was found to decrease as the temperature increases beyond 10ºC whereas that of Propan-2-ol increased at the temperature 20ºC. It then decreased as the temperature increased beyond 20ºC. The loss factor on the other hand was found decreasing as the temperature increases for both Propan-1-ol and Propan-2-ol. This work also reveals that Propan-2-ol at 20ºC followed Debye relaxation equation only at frequency range.
