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. WebAn FTIR spectrum arises from interferograms being ‘decoded’ into recognizable spectra Patterns in spectra help identify the sample, since molecules exhibit specific IR …
