Learning goals
Increase the knowledge of the atomic and molecular structure in the context of the quantum theory, and become familiar with the fundamental aspects of atomic and molecular spectroscopy.
Skills to develop: Competence in analysis and synthesis; Competence to solve problems; Competence in critical thinking; Adaptability to new situations; Competence in applying theoretical knowledge in practice.
Syllabus
Atoms with 1 electron: Schrödinger equation; relationship between magnetic dipole moment and angular momentum, the Stern-Gerlach experiment, spin-orbit interaction, fine and hyperfine structure, Zeeman and Stark effects, interaction with the electromagnetic radiation field - emission and absorption of radiation, radiative transitions and selection rules. Atoms with several electrons: the central field approximation, electronic configurations and spectroscopic notation, spin-orbit interaction, LS and j-j coupling, optical and X-ray spectra, Zeeman and Paschen-Back effects. Molecules: The molecular bonding, electronic structure of diatomic molecules, the H2+ molecular ion, the hydrogen molecule, complex molecules. Molecular spectra: rotational and vibrational levels, electronic spectra. Transitions between atomic and molecular levels; Definition of cross section. Lasers: conditions for laser emission, absorption and gain coefficients, amplitude and phase of laser light.
