Practical exercises on Raman spectroscopy
Raman spectroscopy is, together with infrared spectroscopy, a spectroscopic technique which has gained a lot of importance in the recent years due to its non-invasive character. Both use the vibrational spectra of molecules for the identification and characterisation of substances. Ideally after having attended courses on optical spectroscopy in the second section of the study, the UE Raman spectroscopy course is intended to give a first insight in this technique by performing some simple exercises on research grade instruments (both dispersive as well as FTIR Raman spectrometers), in order to show advantages and disadvantages of different Raman techniques. The actual samples studied are usually connected with actual research fields of the working group experimental physics. These are situated in the areas of physical chemistry of liquids, applied mineralogy (e.g. recent and fossil resins, inclusions in minerals), and botany (pigments on petals).
