Raman spectroscopy is an inelastic scattering phenomenon the probes molecular vibrations to provide a molecular fingerprint of materials. Currently, there are six major types of Raman spectroscopy in use today, which are: Spontaneous Raman Spectroscopy, Resonance Raman spectroscopy (RRS), Surface Enhanced Raman spectroscopy (SERS), Coherent Anti-Stokes Raman Scattering (CARS), Stimulated Raman Spectroscopy (SRS) and Spatially Offset Raman Spectroscopy (SORS).
Fourier transform infrared spectroscopy, or FTIR, is a vibrational spectroscopy method which is based upon the measurement of specific frequencies which occur between chemical bonds in a given material. Interestingly, as materials may be unique in chemical nature, so are the infrared spectra which they yield, resulting in a unique “fingerprint” for a given material. As such, this makes FTIR a very resourceful tool for such things as:
