The depolarised light scattering intensity from hquid argon has been measured relative to the 991 cm-l Raman line of benzene, whose absolute intenstty is known-The mean-square induced polarisability anisotropy is (10.6 f 1.0) X 10Vs' cm6, approximately five times larger than prevrously reported, but
dynamics calculations on the time dependence of the anisotropic potentiat experienced by a probe molecule in argon, are presented. The calculations were performed for Ar densities of 100,300,500 and 784 amagat and T= 160 K. CoUecGve motions clearly manifest themselves at higher densities, in particu

## Abstract Dynamic light scattering experiments were performed on solutions of the bacteriophages T7 and T4B in order to obtain the rotational diffusion coefficients of these phages. Correlation functions were determined from the depolarized intensity scattered in the forward direction. The appara
