Abstract
Experimental translational and rotational diffusion data for about 30 molecules dissolved in n-hexane are compared with the predictions of s lip hydrodynamics as well as the hard body kinetic theories of Enskog and Evans. The results indicate that slip hydrodynamics and Enskog the ory are generally successful in quantitatively predicting both transla tional and rotational diffusion coefficients while Evans' generalizati on of Enskog theory appears to overestimate the effects of correlated collisions.
