Use of Stokes and anti‐Stokes Raman scattering for new applications

We show the interest in recording both Stokes and anti‐Stokes Raman spectra in two peculiar applications. In one case, the comparison between these two parts of the spectrum, measured at one temperature only, allows to distinguish between first‐ and second‐order phonon bands. In the second example, the difference between Stokes and anti‐Stokes spectra provides separation between vibrational and emission lines. We describe the different stages needed in the measurements and data treatment.
