    Diffusion in Binary Liquid Mixtures of non Electrolytes
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1978, 74 (02), 1978) Barrie, James A.; Dawson, Ray B.; Sheppard, Richard N.
    Self diffusion coefficients at 25 'C for octamethylcyclotetrasiloxanc in binary mixtures with benzene and carbon tetrachloride have been measured by pulsed field gradient pulsed n.m.r. A comparison is made of the diffusion data for these systems with the predictions of the Darken equation and of simple hard sphere theory expressions; neither approach gives a satisfactory representation to the data. Friction coefficients, Li, for octamethylcyclotetrasiloxanc have been evaluated for part of the composition range.
