abstract = {The thermal diffusion, also called the Ludwig-Soret effect,
of aqueous solutions of ethylene glycol oligomers, crown
ethers, and glycerol are investigated as a function of
temperature by Thermal Diffusion Forced Rayleigh Scattering
(TDFRS). The Soret coefficient, $S_{\rm{T}}$, and the
thermal diffusion coefficient, $D_{\rm{T}}$, show a linear
temperature dependence for all studied compounds in the
investigated temperature range. The magnitudes and the
slopes of $S_{\rm{T}}$ and $D_{\rm{T}}$ vary with the
chemical structure of the solute molecules. All studied
molecules contain ether and/or hydroxyl groups, which can
act as acceptor or donor to form hydrogen bonds,
respectively. By introducing the number of donor and
acceptor sites of each solute molecule, we can express their
hydrogen bond capability. $S_{\rm{T}}$ and $D_{\rm{T}}$ can
be described by an empirical equation depending on the
difference of donor minus acceptors sites and the molecular
weight of the solute molecule.},
