Electrical resistance and dielectric constant anomaly in the critical liquid mixture methanol + cyclohexane

Abstract

The electrical resistance R and the dieletric constant ∈ of the critical binary liquid mixture methanol plus cyclohexane has been measured near the critical point at five different spot frequencies from 10-100 kHz. The data are analysed using a nonlinear least squares routine. The fit is equally good for an α (=0·1) divergence or a 1-v (=0·35) divergence of dR/dT and d∈/dT. Additional reasons are advanced to indicate that the α divergence is a better description.
