Learning outcomes

The lecture gives an overview of the quantum description of the interactions of electromagnetic field with matter. The lecture includes a description of the electron, vibration and magnetic transitions of molecules, transfer of excitation energy, relaxation processes, and nonlinear laser effects. The aim is to provide basic information necessary for understanding the optical spectroscopy, NMR and EPR spectroscopy and laser functions.
Knowledge of general physics (basics of mechanics, thermodynamics, optics and atomic physics), basic knowledge of quantum mechanics from the course Quantum theory I. Knowledge of methods of mathematical analysis (derivation, integrals, differential equations, Fourier transformation)
