    • Abstract

       

      Dielectric properties of nitriles have been studied using time domain reflectometry in the frequency range of 10 MHz to 10 GHz over the temperature range of 0°C to 45°C. The calculated dielectric relaxation parameters are compared with values for the corresponding n-alcohols. The dielectric behaviour in n-nitrile systems is quite different from the corresponding behaviour in n-alcohols. The dipoles in n-nitrile systems show a tendency to remain antiparallel, unlike in alcohol systems. The activation energy decreases with the increase of molecular size, whereas in hydrogen bonded liquid it increases.
