Abstract:-About the molecular interactions between molecules. Kirkwood correlation factor g was also
calculated to gain information In this paper precisely measured values of static permittivity (ε0 ) and
permittivity at optical frequency (ε ∞) of the binary mixtures of bromobenzene (BB) and 1- heptanol (1-
HeOH) of varying concentration at 303 0C are reported. ε0 and ε∞ were found to deviate from ideal
behavior with concentration variation. The excess static permittivity was calculated from measured data.
The character change of ε0 is presented by its excess value as a function of composition of mixture. The
excess property was qualitatively analyzed to gain valuable information regarding orientation of electric
dipoles in polar liquids. Earlier reported results of the binary mixtures of BB + MeOH (methanol), BB +
1-PrOH (1-propanol) and BB + 1-BuOH (1-butanol) are compared with the data of BB + 1-HeOH.
Effect of increase in chain length of primary alcohol on the dielectric properties of the mixtures of BB +
alcohol is discussed. Measured static permittivity and refractive index data of BB + 1-HeOH mixtures
are also compared with those estimated by different mixing rules.
