After a review of basics of atomics & molecular spectroscopy, this lecture describes the basics of absorption (microwave and infrared) and Raman scattering high-resolution spectroscopy of small polyatomic molecules. We review the difference molecular movements and their interaction with light.
Contents:
- Born and Oppenheimer hypothesis.
- Molecular rotation and vibrations.
- Vibration coordinates.
- Vibration-rotation Hamiltonian in classical mechanics.
- Vibration-rotation Hamiltonian in quantum mechanics.
- Vibration-rotation energy at order 0.
- Generalities on transitions.
- Vibration-rotation energy at order n.
The lecture is completed by exercises to learn how to analyze simple spectra.
