The Determination of the Critical Exponents v, y and η of the Binary Systems Decane‐Chlorex and Dodecane‐Chlorex by Light Scattering

Abstract

AbstractFrom our measurements we have obtained a mean value of η = 0.05. The reciprocal scattered intensity at the critical concentration extrapolated to zero angle follows the power‐law Ic,o−1 ∝[(T ‐ Tc)/Tcy]. We have found deviations from this power‐law in the temperature range [(T ‐ Tc)/Tc]≤ 3 ·10−5. These deviations may be explained by taking into account the uncertainty in the critical concentration with the help of the “pseudospinodal curve” concept, as proposed by Chu, Schoenes, and Fisher.
