| Abstract: | Complex permittivity
of mixtures of fluorobenzene (FB) and methanol (MeOH) over a wide range of
concentration (0.0-1.0) has been measured at various temperatures. Vector
network analyzer (VNA) operating in the frequency range
0.3 MHz-3.0 GHz is used to obtain complex permittivity spectra of the liquid
samples. Complex permittivity of these samples at two spot frequencies 9.1 and
19.61 GHz is also measured using standard microwave benches. Measured values of
the dielectric loss ( ) have
been plotted against dielectric constant ( ) in a complex plane for MeOH, FB and their mixtures. Various
dielectric parameters like relaxation time ( 0), static dielectric constant (ε0)
and high frequency limiting dielectric constant ( ) have been obtained from these
curves. Obtained dielectric parameters are used to evaluate Kirkwood
correlation factor (g), Bruggeman
parameter (fB) and
thermodynamic parameters. These parameters have been interpreted in terms of
molecular interaction between the different molecular species of the liquid
mixtures. |
