The infinite dilution diffusion coefficients of methane, ethane, n-propane, n-pentane, n-heptane, n-decane, n-dodecane, and n-tetradecane have been measured in n-octane using the Taylor dispersion technique in the temperature range 304-435 at 1.72 x 10/sup 6/ N/m/sup 2/. Using the framework of the rough hard sphere theory, the values of the translational-rotational coupling parameter have been determined for each solute-solvent pair at each temperature. The coupling parameter was found to be independent of temperature over the entire temperature range of the experiments performed and it has the same value for solutes ranging from n-pentane to n-tetradecane. A calculation scheme is presented for accurate determination of infinite dilution diffusion coefficients for a wide range of solutes in n-octane at a wide temperature range.
