How does ft raman work
http://www2.chem.uic.edu/tak/chem52413/notes17/PerkinElmer_Raman20Questions.pdf WebRaman microscopy (µ-Raman) is the combination of conventional light microscopy and a unique chemical identification by Raman spectroscopy. Both techniques are quite powerful on their own, but when combined they offer the possibility to chemically examine smallest objects (> 0.5 µm) and thus, they link spectral with spatial information.
