    Arrhenius activation energy of reactions that are almost diffusion-controlled
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1977, 73 (04), 1977) Logan, S. R.
    Expressions are derived for the Arrhenius activation energy (Ea) of bimolecular reactions in solution occurring on almost every collision, in terms of the parameter B from the temperature-dependence of the solvent viscosity. Applied to a single reaction occurring with constant parameters of reaction in solutions of variable viscosity and variable values of B, it is deduced that over these various solvents, Ea should be a linear function of B, with an intercept approximating to RT, regardless of the magnitude of the (small, constant) critical energy requirement, E* of the reaction. This conclusion negates a recent assertion that the intercept is a measure of E*.

    Photo-effects on benzoylferrocene in hydroxylic solvents
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1977, 73 (04), 1977) Heaney, Elizabeth K.; Logan, S. R.; Powell, John A.
    It is shown that, contrary to earlier claims, the illumination of benzoylferrocene in a primary alcohol with light of around 300 nm does not cause photoionization to the benzoylferricenium ion and the solvated electron.
