Abstract
Recent studies of quasi-free molecular motion in liquids will be presented. Of particular interest is the inertial regime of motion which occurs significantly only if the free rotational period is comparable with the effective collisional frequency in the liquid. Results on the isomerism of stilbene and on the anisotropy decays for aniline in solution have exposed regions where the motion is nondiffusive. The results are compared with current statistical mechanical theories.
