✦ Synopsis

From the adjustment of theoretical orientational correlation functions, based on Steele memory function theory, with experimental correlation functions, the mean-squared torques are measured for C2D2 and COz mixed with krypton up to 468 amagat. A comparison is made with results obtained from spectral moment measurements. Below a value for the mean-squared torque equal to 35 X lo4 cm-', the two methods give the same results. Above this value, the theoretical correlation functions do not agree with the experimental ones and the spectral moments method should be used. Advantages and disadvantages of the two methods are discussed.

The mean-squared torque (C 2) acting on a N20 molecule mixed with xenon or carbon dioxide is reported as a function of the density p of the perturbing gas, up to 110 amagat. It is shown that the experimental slope (C2)/p is fifty percent bigger in the case of carbon dioxide. Taking into account the
