RAMAN SPECTROSCOPY

Outline:

The rotation of molecules. The rotational selection rules. Nuclear statistics. The vibrations of molecules. Rotation-vibration spectra of diatomic molecules. The vibrations of polyatomic molecules. Group theory and molecular vibrations. Anharmonicities (Coriolis forces, Inversion doubling).

Introductory experiments to the Raman spectroscopy on biological systems, polymeric compounds and new materials. Raman calibration procedures.

Micro-Raman imaging of heterogeneous polymeric mixtures. Raman polarization measurements of stretched polymers. Determination of polymer crystallinity via FT-Raman spectroscopy. Comparison of micro-Raman (with visible excitation laser), FT-Raman (with near-IR excitation laser) and FT-IR measurements. High-temperature Raman.
