Using a Lennard‐Jones (12‐6) potential (for which numerical computations of the transport coefficients also exist)⁷ the measured temperature dependence cannot be described even approximately. Although this model also predicts a minimum of α in the range of negative values, the absolute value of α in this minimum would differ by about one order of magnitude.
