Query: Corrections to Scaling in the Hydrodynamic Properties of Dilute Polymer
  Solutions   We discuss the hydrodynamic radius $R_H$ of polymer chains in good solvent,
and show that the leading order correction to the asymptotic law $R_H \propto
N^\nu$ ($N$ degree of polymerization, $\nu \approx 0.59$) is an ``analytic''
term of order $N^{-(1 - \nu)}$, which is directly related to the discretization
of the chain into a finite number of beads. This result is further corroborated
by exact calculations for Gaussian chains, and extensive numerical simulations
of different models of good--solvent chains, where we find a value of $1.591
\pm 0.007$ for the asymptotic universal ratio $R_G / R_H$, $R_G$ being the
chain's gyration radius. For $\Theta$ chains the data apparently extrapolate to
$R_G / R_H \approx 1.44$, which is different from the Gaussian value 1.5045,
but in accordance with previous simulations. We also show that the
experimentally observed deviations of the initial decay rate in dynamic light
scattering from the asymptotic Benmouna--Akcasu value can partly be understood
by similar arguments.
