dc.description.abstractDielectric relaxation in four ternary systems of benzotrifluorides consisting of benzotrifluoride, 2-chloro-benzotrifluoride and 2-amino-benzotrifluoride has been studied at 9.408 GHz over a temperature range 290-330 K. Static dielectric constant and refractive index of individual components of these benzotrifluorides and their mixture compositions have been measured. The measured dielectric data of these benzotrifluorides have been discussed in terms of distribution of relaxation time and its variation with temperature. The process of dipole orientation and viscous flow in these liquids has been discussed on the basis of rate theory. Various thermodynamical parameters viz. entropy,enthalpy and free energy of activation have been determined using measured dielectric data. These calculated thermo dynamical parameters for relaxation processes and viscous flow processes confirm existence of both inter-molecular and intra-molecular orientations in these substituted benzotrifluorides. These polar compounds under investigation have been used in pure form as dielectric samples. The methods used to obtain results presented in this paper are based on the measurement of standing wave pattern in a dielectric medium.en_US
