Microwave absorption and relaxation processes of some binary systems of non_rigid polar molecules in benzene solutions at different temperatures

An investigation on molecular dynamics of binary mixtures of anisole and isobutanol in benzene at 303, 313 and 323K

“…Similar conclusions were given by Mehrotra et al [22]. Gopal lal Sharma et al [23] have reported that a polar liquid mixture having both components as associative or non-associative has a single relaxation time whereas if one of them is associative and other one is non-associative, it has two relaxation times. But in this case obtained results are contradictory to the views reported by Gopla Lal Sharma et al But though anisole, isobutanol are associative in nature, two relaxation times were observed in them.…”

“…The value of ΔF τ for all the three concentrations of the mixture at studied temperature is less than the corresponding value of the pure components. Similar views have been reported by Sharma et al [23] for the mixture of acetates. In the mixtures, the molar free energy of activation for the dielectric process decreases with the increase of temperature as in pure states.…”
