| Abstract: | The authors have studied the mechanism of dielectric relaxation of primary amines from the point of view of the following characteristics : relaxation time distribution, activation energy, resultant behaviour of autocorrelation function of the orientational polarisation, spectral density of energy as a function of temperature and chain length of the aliphatic type molecules.The analysis of the relaxation mechanism is made on the basis of semi-empirical macroscopic model of Davidson-Cole. The relaxation mechanism can be analysed as a function of the combined effects of intermolecular and intramolecular relations which are related to the dipolar behaviour of amine group as well as the effect of hydrocarbonic aliphatic chain. |
