ResumoOur two groups have measured independently the “Rayleigh linewidth” (Γ), the reduced compressibility (ϖϱ/ϖμ)T, and the pressure (P) of SF6 along the liquid and vapor sides of the coexistence curve. We find that (ϖϱ/ϖμ)T = 1.67 × 10-10 (1 - T/Tc)-1.22 ± 0.015g2erg-1cm-3 and (∂P/∂T)lχ = (7094 ± 0.1) × 105 dyne/cm2 ° We analyze our linewidth measurements in terms of the Kadanoff-Swift-Kawasaki mode-mode coupling theory using estimates for the viscosity and correlation range.
