The aim of this paper is to present the NH<sub>2</sub> dielectric behaviour in the primary amines for the importance it bears in the interaction of aminoacids and proteins and their influence in the electric conduction processes. For that, the dielectric properties of 1-propylamine, 1-butylamine and 1-pentylamine have been studied. Measurements were performed between room temperature and −180 °C in the low frequency range and micro-waves measurements were done between −40 °C and 25 °C. The isofrequency recordings of dispersion ε′ and absorption ε′′, for these three primary amines, show clearly the relaxations and the effect of the aliphatic chain length.
