1.03 | Molecular Point Groups and Orbital Diagrams

April 3rd, 2023. In this third lecture, we continue with the molecular point groups, we are now at the final examples, followed by some practise on how to assign the point groups using the flowchart handed out int he previous lecture. At the end, we discuss the properties of a group and we saw that multiplication of different symmetry operations on a molecule (Ammonia) generates another symmetry operation that was also part of the group. From where we established the fundamental properties of a symmetry group. At the end of the lecture, we started with the basic principles on how to construct simple MO diagrams of diatomic molecules, where we will return in the next lecture. Note: The first 45 minutes only the sound is available due to a technical error of the camera.
