3. Applications

Twenty years ago, the field of application of Raman spectrometry was still very limited, due to the low sensitivity and cumbersome operation of the instruments available. Restricted to research laboratories, the technique was essentially reserved for fundamental studies. Until the 1960s, Raman spectra of all kinds of substances were catalogued and provided essential data for establishing molecular structures and conformations. Over the last ten years, instruments have become increasingly compact, sensitive and easy to use, thanks in particular to...
