Understanding the energetics and structure of aromatic molecules (those containing benzene rings) is important to a large area of chemical science including protein and DNA structure, crystal engineering, nanocarbon solvation and petroleum phase behaviour. For all these fields one potentially important interaction is that between saturated alkyl carbon and the aromatic π system, for which a benzene-cyclohexane represents an ideal model system. Recent calculations benzene-cyclohexane dimers have suggested that the strength of the attraction between the two molecules is stronger than in either benzene-benzene or cyclohexane-cyclohexane dimers. We will use neutron scattering to discover how cyclohexane and benzene molecules arrange themselves when mixed, to further understand this important chemical interaction.
