Abstract
The isothermal compressibility of CCIF3 has been determined by a combination of turbidity and light scattering intensity measurements in the vicinity of the critical point and along the critical isochore to be magnified image for the temperature range 3 · 10−4 ≤ (Tc · Tc)/Tc ≤ 5.5 · 10−2. The critical exponent of the compressibility agrees within the error limits with the results obtained on other one‐component systems, binary fluid mixtures and the three‐dimensional Ising model.
