High pressure self-diffusion coefficients and densities are reported for the binary system tetradecane/methane in a wide range of temperature at Pressures up to 200 MPa. The experimental diffusion data of these mixtures are analyzed in the frame work of the rough hard sphere (RHS) model under application of hard sphere (HS) molecular dynamics simulations for binary mixtures of hard spheres obtained recently in our group. The rotation-translation coupling parameter A shows a weak temperature dependence, falling slightly when the temperature is lowered. The RHS-diamerer for the lighter compound is identical to the value found for neat methane. The value for the RHS-diameter of tetradecane in the mixture is found slightly larger than in the neat retradecane. Both diameters show a slight increase with falling temperature.
