✦ Synopsis
A master equation relating the coherent and incoherent dynamical slructure factors S(q, w) and S,(q, w) is introduced on the basis of physical arguments suggested by previous theories. It is shown that, once S,(q, w) and the fnst six moments of S(o. w) are known, the resulting expression for S(q, w) contains the correct hydrodynamic regime as well as the free particle behaviour. The relationships thus introduced berween the transport coefficients and the molecular quantities are compared to the experimental data for liquid argon. Molecular dynamics data arc also well reproduced.
