Abstract:

The researchers formulated a theory to describe and calculate the dynamical dielectric response of classical interacting molecular liquids in terms of their corresponding static response functions. There are two basic ideas in this approach. One idea is to use a local effective field to tale into account the long range coherent effects of the molecular interactions. These local fields are derived from the static structural properties of the liquid. The other idea to calculate the self-part of the Van Hove correlation function from the solution of a Boltzmann transport equation in phase space in a number conserving relaxation time approximation. This smoothly interpolates between the hydrodynamic and free particle regimes. Thus they obtained an important generalization of previous theories of molecular liquids, which only treated the self-part of the van Hove correlation function in the hydrodynamic limit, that is wo and q-0.
