Temperature dependent dielectric study of n-nitriles in methanol using time domain reflectometry

The dielectric properties of N-nitriles in methanol have been studied using Time Domain Reflectometry (TDR) technique, in the frequency range of 10 MH z to 10 GHz. The calibration method based on least squares fit method has b een used. The dielectric parameters such as static dielectric constant, rel axation time, Kirkwood correlation factor and thermodynamic parameters for the system have been obtained in the temperature range of 0 degrees C to 45 degrees C. The investigated values of dielectric parameters show systemati c change in dielectric values with increase in concentration of nitrile in the solution. (C) 2000 Elsevier Science B.V.
