    2. Roentgen diffraction Elementary crystallography symmetry of the structure, space group symmetry, diffraction of Roentgen radiation, structural factor. Basis of structural analysis data collection, data reduction, phase problem and its solution, improvement of the structural model, structure evaluation.

    3. Crystallography of proteins Macromolecular techniques of crystallization, methods of sitting and hanging drop, inoculation. Experiments of diffraction sources of rtg. irradiation, detectors, cryo-crystallography. Methods of phase problem solution in proteins. Method of molecular transfer. Methods of metal derivatives (SIR, MIR, MIRAS), MAD and selenoproteins. Maps of electron density. Building of structural model and its refinement.

    4. Fluorescence spectroscopy Fluorescence and other luminescence methods, life time, quantum yield. Fluorescence intensity. Switch-out and selfquenching. Excitation and emission spectra. Quasiline fluorescence and fluorescence in solid phase. Spectrometer and measurement procedure.

    5. Techniques of Raman spectroscopy. Elastic and non-elastic dispersion of irradiation (Stokes and anti-Stokes lines). Transition integral and induced polarization. Electronic, resonance and surface increase. Coherent anti-Stokes Raman spectroscopy. Nonlinear effects stimulated, inverse, and hyper-effect.
