    Effect of Water on Proton Migration in Alcoholic Solvents: Part 3.—Conductance of Hydrogen Chloride in Pentan-l-ol at 25°C
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1974, 70 (1-6), 1974) Lisi, R. De; Goffredi, Mario
    Conductance measurements at 25°C on dilute solutions of hydrochloric acid in pentan-1-ol containing small amounts of water are reported. The data were analyzed with the 1965 Fuoss–Onsager conductance equation. The analysis of the dependence of the limiting equivalent conductance viscosity product on chain length of alcohol molecules shows that λ°H+η increases with increasing monomer concentration. This experimental evidence is qualitatively discussed with respect to current theories of the proton-transfer mechanism.

    Effects of water on proton migration in alcoholic solvents. Part 5.—Conductance of hydrogen chloride in methanol at 15, 25 and 35°C and in ethanol and pentan-1-ol at 15 and 35°C
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1978, 74 (05), 1978) Lisi, Rosario De; Goffredi, Mario; Liveri, Vincenzo Turco
    Conductance data are reported for hydrogen chloride in water + methanol mixtures at 15, 25 and 35°C and in water + ethanol and in water + pentan-1-ol mixtures at 15 and 35°C. Measurements were carried out in alcohol-rich mixtures over a water composition range up to about 20 % by weight. The results have been anlysed in terms of the Fuoss–Onsager conductance theory. The temperature dependence of the limiting molar conductance/viscosity product for hydrochloric acid in anhydrous methanol, ethanol and pentan-1-ol, respectively, is considered and discussed with respect to the influence of molecular solvent structure on the proton transfer mechanism.
