Query: Improved simulation method for the calculation of the intrinsic
  viscosity of some dendrimer molecules   A method previously proposed for calculating the radius of gyration and the
intrinsic viscosity of dendrimers is modified to give a more accurate
description of existing experimental data. The new method includes some
features that were not previously considered, namely: a) a correction term to
take into account the contribution of individual friction beads, whose volumes
are not negligible in comparison with the molecule size, b) a realistic
distribution of internal angles between successive beads that define branching
points in the molecule, c) a distribution of distances between branching points
computed from Molecular Dynamics simulations of a small dendrimer with explicit
solvent. Modification a) alone is able to give a good description of the
experimental results obtained for polypropylene-imide with a diaminobutane core
in water, while the simultaneous use of the three modifications is needed to
adequately describe the experimental data of monodendrons and tridendrons of
polybenzylether in THF.
