The goals of this course is to provide a deeper basics of some theories in spectroscopies and to derive the basic relations. The contribution of the classic theories of interaction between electromagnetic radiation and matter are explained, the Fermi golden rule for spectroscopies is derived based on quantum mechanics. The quantum mechanical description of the molecular states is based on several principles and approximations (adiabatic, Born-Oppenheimer approximation, Franck - Condon principle etc.). Both classic and quantum theory of molecular vibrations is shown and the concept of normal vibrations is explained. The effect of molecular symmetry in the spectra is demonstrated. Theoretical nature of resonance spectroscopies (NMR, EPR) is explained.
Knowledge Define the main ideas and conceptions of the subject, describe the main approaches of the studied topics, recall the theoretical knowledge for solution of model problems.
