We shall discuss the molecular-statistical approach to describing the rotational diffusion of anisotropic molecules (rods or disks) in a mean field of liquid crystalline order (nematic or smectic-C). The issues of microscopic stress tensor and its averaging, of the spectrum of relaxation times, of the role of more delicate ordering (e.g. smectic layering or biaxiality), and of the route to the full pair-correlation theory will be considered.
