Abstract

The electrical resistanceR and the dieletric constant э 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 ana (=0·1) divergence or a 1 −v (=0·35) divergence of dR/dT and dэ/dT. Additional reasons are advanced to indicate that thea divergence is a better description.
