Broadly, the field of reaction dynamics helps to obtain atomic level understanding of chemical reaction mechanisms. Our goup is involved in theoretically understanding reactions in gas-phase, important in atmospheric chemistry, reactions in the gas-solid interface, relevant in heterogeneous catalysis and the reactions involing laser-molecule intractions, widely used to control the outcome of desired chemical reactions.
