Abstract
A molecular colloidal fluid of moderately nonspherical axisymmetric molecules interacting via a two-site Yukawa potential is studied by the Brownian dynamics simulation method. The long-time translational self-diffusion coefficient and the rotational self-diffusion coefficient are calculated, at several concentrations and for different anisotropies of the one-particle diffusion tensor. The influence of the one-particle diffusion tensor on the dynamical properties is studied. It is shown that the rotational motion of the tracer molecule can be well described up to high volume fractions over a considerable time interval by the rotational diffusion equation with a state dependent rotational diffusion coefficient.
