摘要：
Using time-domain reflectometry (TDR) technique, we have measured the complex permittivity of tertiary butyl alcohol (TBA)-water mixtures in the frequency range of 10MHz-30GHz, at temperatures 15 degrees C, 20 degrees C and 25 degrees C. The complex permittivity of TBA-water mixture shows Debye-type behaviour. The dielectric parameters such as dielectric constant and relaxation time were obtained from the complex permittivity spectra. The Kirkwood correlation factor and Bruggeman factor have also been determined to investigate inter- and intramolecular interaction among associating liquids.
