Topological methods for non-covalent interactions in solids

The bulk and surface structure of molecular and layered crystals is determined by a delicate balance of non-covalent forces[1,2], which are extremely difficult to model computationally. Lack of chemical insight into these interactions is a limitation in a priori structural design. In this talk, I will present topological approaches that allow the chemist to recover intuitive concepts from density-funcitonal calculations in periodic solids. These include the non-covalent interactions (NCI) analysis, the electron localization function (ELF), and the molecular electrostatic potential (MEP). Chemical features such as lone-pairs, pi-stacking, weak hydrogen bonds, caged electrons... come together in the experimental crystal structure and can be identified directly using the aforementioned tools.
