Abstract

In this paper microwave dielectric relaxation times of cellosolves in dilute solutions of carbon tetrachloride are reported. These have been calculated using Higasi\´s equations by measurement of permittivity ε\´ and dielectric loss ε" at 9.83 GHz. It is observed that average relaxation time τ₀ and relaxation time for overall rotation τ₁ both increases while relaxation time τ₂ for group rotation decreases with the increase in molecular size. These results have been compared with earlier relaxation data in benzene solutions and pure liquid state and discussed
