The theoretical chemistry group led by Grant Hill employs the latest advances in local electron and explicit correlation to reduce the computational cost of highly accurate wavefunction methods such as coupled cluster theory. To enable these methods to be used for a wide variety of chemical systems, the group designs, develops and optimises Gaussian basis sets that are utilised to construct the molecular orbitals necessary for the Schrödinger equation. Applications of these methods are currently focused on non-covalent interactions, such as π-stacking and hydrogen bonding. While significantly weaker than standard covalent bonds, these interactions are fundamental to the process of molecular recognition and even define the structure of DNA. A deeper understanding of the processes involved could lead to advances in nanobiotechnology and in the treatment of cancer.
