| Non-covalent interactions play an important role in determining the properties and behaviors of biomolecules and their interaction with drugs and proteins. π-π Interaction is particularly prevalent in heterocyclic molecules such as quinoline. While many studies have involved dimers of benzene, fewer have involved dimers of heterocyclic molecules. Quinoline dimers have not been explored in spite of their prevalence in nature and pharmaceuticals. Benzene is the classic example, where it has been shown both experimentally and by ab initio calculations that the optimal geometry of such an interaction is T-shaped, in contrast to naphthalene where it is parallel. In this paper, we communicate the results of our studies on quinoline dimers by various methods including MP2 and DFT, with various basis sets and counterpoise corrections. Dimer geometries studied included "sandwich", "T-shaped," and "parallel displaced." The strategy utilized geometry optimizations and concomitant calculations of single point energies. |
