Learning goals

Deepen knowledge about the atomic and molecular structure in the context of quantum theory and get familiar with the essential aspects of atomic and molecular spectroscopy.


1. Hydrogenoid atoms: Schrödinger equation for hydrogenoid atoms; relation between magnetic dipole moment and angular momentum; Stern-Gerlach experiment; electron spin angular-momentum; spin-orbit interaction; fine and hyperfine structure of energy levels. Atoms in the presence of external fields: Zeeman and Stark effects. Interaction of hydrogenoid atoms with the electromagnetic radiation field: radiation emission and absorption; Radiative transitions and selection rules.

2. Polielectronic atoms: central field approximation; periodic table; electronic configurations and spectroscopy notation. Spin-orbit interaction; L-S and j-j coupling. Optical and X-ray spectra. Interaction with external magnetic fields: Zeeman and Paschen-Back effects.

3. Molecules: The molecular connection; electronic structure of diatomic molecules; H2+ hydrogen molecular ion; hydrogen molecule; complex molecules. Molecular spectra; rotational and vibrational levels; molecular electronic spectra.

4. Transition processes between atomic and molecular levels; notion of efficient section.

5. Lasers: conditions for laser emission; absorption and gain coefficients; amplitude and laser light phase.
