Preferred Abstract (Original):

The results of ultrasonic absorption and velocity measurements for the system perfluoromethylcyclohexane-carbon tetrachloride are presented. In addition, viscosity measurements were made. Ultrasonic absorption at 5, 7, 10, 15, 21, and 25 MHz, above critical temperature Tc, is analyzed using the dynamic scaling theory of Ferrell and Bhattacharjee. The values of alpha/f2 vs f-1.06 show a good agreement with the theory. The experimental values of alpha/alpha c for the binary mixture are compared to the scaling function F(omega*).
