The aim of the course is to give a detailed understanding of molecular orbital theory with applications. During the course, basic and advanced methods in quantum chemistry are presented. An important part of the course is the practical computer exercises, in which you get hands-on experience with simple quantum chemical calculations, such as Hartree-Fock and density functional theory. Furthermore, you learn how to approach a chemical reaction from a quantum chemical perspective by determining potential minima, transition states, force constants, zero-point energy etc.
