abstract = {We employed thermal diffusion forced Rayleigh scattering
(TDFRS) to investigate the chain length dependence of the
thermal diffusion behavior of short glycols in ethanol. We
studied three glycols, monoethylenglycol (MEG),
diethylenglycol (DEG) and triethylenglycol (TEG), in an
ethanol solution. In contrast to the polymer
polyethylenglycol, the shorter glycols used within the
framework of this study are completely soluble in ethanol,
at least for low molar fractions. In order to guarantee a
good solubility of the glycols, the measurements were
limited to molar fractions of $10\%$ and $20\%.$ As the
different glycols only differ by their chain length it will
be possible to deduce its influence on the thermal diffusion
properties. Due to the fairly short persistence length of
the glycols, D(T) reaches already for the dimer a plateau
value. This finding agrees with simulation results.
Furthermore, the thermal expansion and the kinematic
viscosity are measured to investigate if empirical
correlations seen for other systems could be confirmed.},
