Light scattering near the plait point of a ternary liquid mixture: Ethanol–water–chloroform

Abstract

Critical exponents γ x and ν x obtained from the angular distribution of scattered intensity measured at relatively large temperature distances [t= (T−T c )/T c ≳5×10−4] from the plait point gave values of 1.40±0.02 and 0.73±0.04 which are in good agreement with the values γ x =γ/(1−α) =1.23/(7/8) =1.41 and ν x =ν/(1−α) =0.63/(7/8) =0.72 obtained by renormalization of critical exponents for binary fluid mixtures.
