      abstract     = {We investigate the thermodiffusive properties of aqueous
                      solutions of lithium chloride, using thermal diffusion
                      forced Rayleigh scattering in a concentration range of 0.5
                      – 2 mole per kg of solvent and a temperature range of 5 to
                      45°C. All solutions exhibit non-monotonic variations of the
                      Soret coefficient $S_T$ with concentration exhibiting a
                      minimum at about one mole per kg of solvent. The depth of
                      the minimum decreases with increasing temperature and shifts
                      slightly towards higher concentrations. We compare the
                      experimental data with published data and apply a recent
                      model based on overlapping hydration shells. Additionally,
                      we calculate the ratio of the phenomenological Onsager
                      coefficients $L_{1q}'/{L_{11}$ using our experimental
                      results and published data to calculate the thermodynamic
                      factor. Simple linear, quadratic and exponential functions
                      can be used to describe this ratio accurately and together
                      with the thermodynamic factors the experimental Soret
                      coefficients can be reproduced. The main conclusion from
                      this analysis is that the minimum in the Soret coefficients
                      results from a maximum in the thermodynamic factor, which
                      appears itself at concentrations far below the experimental
                      concentrations. Only after multiplication with the
                      (negative) monotonous Onsager ratio does the minimum move
                      into the experimental concentration window.},
