Fourier transform -Raman spectroscopy

With motion of the moving mirror, the two beams undergo constructive and destructive interference, so that the detector signal will be maximum when 2x = ink (m is an integer) and a minimum when 2x = (m + 1 /2)k. For a single input wavelength, the detector output is a sine wave of the form [Pg.226]

Assuming the mirror velocity is constant, equal to F (centimeters per second), then X — Ff, and [Pg.226]

Of fundamental importance to FT-Raman performance is the relationship between mirror travel and resolution. The precision with which a sine wave frequency may be determined increases as the number of wave periods increases, for reasons ultimately related to the uncertainty principle. The longer the mirror travel, the more periods are observed, and the greater the precision. Increased precision takes the form of higher resolution and smaller instrumental linewidth. Mathematically, the resolution of an interferometer, Sv, is related to the maximum mirror travel. Axmax. according to Eq. (9.6) (20) [Pg.227]

The disadvantages of FT-Raman compared to dispersive systems lie mainly in the area of SNR and detection limits. The various expressions for SNR for FT-Raman were discussed in Section 4.6, but some additional comments are useful here. Division of the signal for a particular wavelength, SitM, by the noise given by Eq. (4.34) yields [Pg.230]

Fourier transformation techniques in spectroscopy are now quite common—the latest to arrive on the scene is Fourier transform Raman spectroscopy. In Chapter 3 1 have expanded considerably the discussion of these techniques and included Fourier transform Raman spectroscopy for the first time. [Pg.468]

Raman spectroscopy, because of its versatility and wide applicability, has been used for a wide range of art historical and conservation science (Edwards 2000) and archaeological applications (Smith and Clark 2004). Fourier transform Raman spectroscopy (FTRS) in particular has the advantage of being a reflective method which allows direct, nondestructive analysis. It can also be used through a microscope to allow the characterization of small samples. [Pg.90]

Conventional Raman spectroscopy cannot be applied directly to aqueous extracts of sediments and soils, although it is occasionally used to provide information on organic solvent extracts of such samples. Fourier transform Raman spectroscopy, on the other hand, can be directly applied to water samples. The technique complements infrared spectroscopy in that some functional groups, eg unsaturation, give a much stronger response in the infrared. Several manufacturers (Perkin-Elmer, Digilab, Broker) now supply Fourier transform infrared spectrometers. [Pg.29]
