Description	269-275 The complex dielectric spectra of binary mixture of triethylene glycol [TEG] + water have been carried out at different concentrations and temperatures (0 °C, 5 °C, 10 °C, 15 °C, 20 °C and 25 °C) in the frequency range of 10 MHz to 30 GHz using time domain reflectometry technique. The static dielectric constant (ε<sub>0</sub>), relaxation time (τ), Kirkwood correlation factor (<em>g</em><sup>eff</sup>), excess permittivity (ɛ<img src='http://www.niscair.res.in/jinfo/ezero.gif' border=0> ), thermodynamic parameters (activation enthalpy and entropy) and Bruggeman factor (<em>f</em><sub>B</sub>) have been determined for binary mixtures. The Bruggeman model for the nonlinear case has been fitted to the dielectric data. These dielectric parameters confirm that the intermolecular homogeneous and heterogeneous hydrogen bonding vary significantly with the increase in concentration of the triethylene glycol in water mixtures.
