  The dielectric properties of Butan-1-ol with acetic acid mixture have been
studied in the frequency range 10 MHz to 20 GHz using time domain spectroscopy
in the reflection mode, at various temperatures (i.e. on 288 K, 298 K, 308 K
and 318 K) and at eleven different concentrations. Dielectric parameters such
as static dielectric constant and relaxation time have been determined. Excess
dielectric constant, Excess inverse relaxation time, Kirkwood correlation
factor and the thermodynamic parameters ({\Delta}H & {\Delta}S) have been
estimated using these dielectric parameters. A drastic change in molecular
structure of Butan-1-ol with acetic acid mixture observed due to strong
intermolecular association among the molecules of complex sysytem.
Thermodynamic parameters explored to insight molecular structures changes of
mixtures at different temperatures.
