Annotation -
Molecular spectroscopy course provides an overview of basic molecular spectroscopy methods. Quantitative analysis is based on the Lambert – Beer law that is derived from the radiation transfer equation. This derivation makes possible an evaluation of the Lambert – Beer law accuracy in boundary cases and discussion of limitations of its relevance. The molecular spectroscopy methods are presented using uniform theoretical principles. The Born–Oppenheimer approximation (BOA) is the starting point since allows a decomposition of the problem (Schrodinger Equation) to electron and nuclear parts. The nuclear part is solved partly from point of view of the rigid (and semirigid) rotor providing a quantum mechanical frame for the rotational spectroscopy, partly as nuclear vibrations. These vibrations are solved using harmonic (anharmonic, Morse) oscillators whereas the main attention is paid to so called “normal vibration coordinations” that the make straightforward solution of vibrational spectra of polyatomic molecules possible. Electronic spectroscopy that is on the other side of BOA , is described in terms of quantum chemistry molecular orbitals. A special attention is also paid to photoelectron spectroscopy methods (UPS, XPS, ESCA) as well as to NMR principles that is on opposite side of spectra. In frame of the molecular spectroscopy course, rudiments of experimental technics (absorption, emission, scattering) as well as advanced spectroscopic methods (using tunable monochromatic sources, FT technics, nonlinear spectroscopy etc.) will be described. An integral part of spectroscopy education is, of course, molecular symmetry, group theory and their excellent applications in molecular spectroscopy.
