Quantum chemistry lies at the heart of the modern description of the nature of chemical bonds and the interactions of atoms and molecules with electromagnetic radiation. In the course chemical bonding and spectroscopy you will deepen your knowledge on the quantum chemical principles that govern the assembly of atoms into molecules. Chemical bonding is mediated by Coulomb forces and electron spin. Spectroscopy enables to determine the geometric and electronic structure of molecules experimentally and provides detailed information on the chemical and functional properties of molecules.
