Specific group–group interactions: determination of the enthalpies of specific group–phenyl interactions by gas–liquid partition chromatography

Gas chromatographic studies have shown that the enthalpy of the weak interaction of a polar or related group (e.g. vinyl, amino, carbonyl, or nitro group) in a sample molecule with the phenyl group in a stationary liquid alters markedly from –0.1 to –1.7 kcal mol–1 with the polar or related group.
