The non-covalent interactions between aromatic rings are of fundamental importance in large number biological and chemical processes. Examples include protein tertiary structure, DNA base stacking, supramolecular chemical recognition, crystal engineering and petroleum phase behaviour. The local structure of aromatic liquids is a delicate balance between dispersion attraction and electrostatic forces due to the uneven distribution of charge over the molecules. An excellent model system with which to study the effect of charge distribution in aromatic liquids is hexafluorobenzene, which has a similar properties (boiling and melting points) and structure to benzene but with an opposite distribution of charge. Here we will study changing this charge distribution effects the local arrangement of molecules in benezene:fluorobenzene mixtures.
