Molecular Spectroscopy
Prerequisiti
Basic knowledge of mathematical analysis, linear algebra, classical physics, quantum mechanics and physical chemistry.
Programma
The course aims at providing the theoretical fundations of modern molecular spectroscopy, particularly of vibrational and rotational spectroscopies.
Featured arguments. Classical and quantum mechanical nuclear Hamiltonian. Expansion of ro-vibrational Hamiltonian. Second order vibrational perturbation theory (VPT2, DVPT2 and GVPT2). Vibrational spectroscopy: normal modes of vibration, anharmonicity, fundamental-, overtone-, and combination- vibrations, infrared spectroscopy and Raman spectroscopy. Rotational and ro-vibrational spectroscopy: rigid rotor approximation and centrifugal distortion, spectroscopic parameters and vibration-rotation interaction, line broadening and spectral line shapes.
Obiettivi formativi
The course aims at: providing and deepening the knowledge on molecular spectroscopy, providing the fundamentals for understanding the rotational and vibrational spectroscopic behavior of gas phase molecules, and presenting the theoretical treatment of the nuclear motion in molecules.
