Molecular Spectroscopy

Academic year 2022/2023
Lecturer Nicola Tasinato

Integrative teaching


Examination procedure

Oral exam and seminars


Basic knowledge of mathematical analysis, linear algebra, classical physics, quantum mechanics and physical chemistry.


The course aims at providing the theoretical fundations of modern molecular spectroscopy, particularly of vibrational and rotational spectroscopies.

Featured arguments. Light – matter interaction.  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.
