• Complex dielectric permittivities in <I>ortho</I>- and <I>para</I>-bromoanisoles and β-bromophenetole in the liquid state have been measured in 1.6, 3.17, and 3.49 cm microwave regions at different temperatures. The dielectric data were analysed in terms of molecular and intramolecular relaxation times. The values of methoxy group relaxation times and its contribution to total polarization obtained in the liquid bromoanisoles have been compared to the corresponding values in dilute solutions reported in literatures. Activation energy for dielectric relaxation and viscous flow in all the cases have also been obtained in all the liquids.
