Query: Relating monomer to center-of-mass distribution functions in
  macromolecular fluids: extension to arbitrary systems   In the framework of the polymer reference interaction site model (PRISM)
extended to incorporate the centers of mass (CM) of the groups of monomers
constitutive of the macromolecules as auxiliary sites, a general relationship
between the monomer-monomer and CM-CM pair correlation functions is derived for
arbitrary mixtures of macromolecules of arbitrary structure. It extends
previous results for homopolymer fluids and should be useful to develop
semi-analytic coarse-grained descriptions of complex fluids.
