Evidence of Nonzero Critical Exponentηfor a Binary Mixture from Turbidity and Scattered Light Intensity Measurements

Measurements of the turbidity and of the intensity of light scattered by a cyclohexane-aniline mixture in the vicinity of the critical point allow us to verify that scaling laws correctly describe the observed phenomena and yield precise values of the critical exponents γ, ν, and η, of the correlation length ξ, and of (∂μ∂c)P,T.
