Sample modulation interferogram points

Bouwman and Freriks (18.19) have also noted the advantages of FT spectroscopy and have used this technique to study the adsorption of CO on a silica-supported nickel catalyst at temperatures between 70 and 180°C. These authors point out that FT spectroscopy is particularly advantageous for in situ observation of heated samples since the radiation emitted by the sample is not modulated by the interferometer and hence does not contribute to the fluctuating portion of the interferogram. [Pg.25]

Fig. 6.4 Interferogram reconstruction. Modulation period is n times the sampling time (here for n = 6). n interferograms (each of m points) are recorded, with different phases of the modulation with respect to the sampling grid. Through proper selection... Fig. 6.4 Interferogram reconstruction.
