    Order-Disorder Transitions in Substituted Adamantanes
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1977, 73 (09), 1977) Clark, Timothy; Knox, Trevor Me. O.; Mackle, Henry; McKervey, M. Anthony
    Order-disorder transitions in 1- and 2-methyladamantane, 1,3-dimethyiadamantane, 1,3,5- trimethyladamantane, 1,3,5,7-tetramethyladamantane and in the 1-halogenoadamantancs have been investigated by differential scanning calorimetry. The effects of substituent groups on the disordered phase behaviour of these molecules are discussed.

    Pre-melting Transitions in Caged Hydrocarbons, a General Theory of Disorder in Plastic Crystals
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1974, 70 (07), 1974) Clark, Timothy; McKervey, M. Anthony; Mackle, Henry; Rooney, John J.
    rhe results of differential scanning calorimetry studies on caged hydrocarbons have been used, with existing data, to propose a new interpretation of orientational disorder in plastic crystals. New empirical relationships are reported between the entropy of transition, plastic crystal range and molecular shape.
