From the Power Spectrum, the measurement region and the level of noise in that region are identified. Looking at the spectrum in Figure 2, the signal intensity in the vicinity of 2000 cm-1 is strong and then becomes weaker on either side of this value. On the long wavelength side, the signal reaches almost zero at 350 cm-1, which indicates that measurements cannot be made at longer wavelengths

from publication: Spectrally high-resolved infrared spectra from Fourier transform experiments are often used to determine atmospheric parameters. Reliability of results depends octahedral complexes and splitting of the absorption bands in FTIR spectra of 57Fe internal field nuclear magnetic resonance and Mössbauer spectroscopy Experiences from several years use of FTIR spectrometry in flue gas analysis are described in this report. One implication, among others, of the FTIR is that Predicting the chemical composition of juvenile and mature woods in Scots pine (Pinus sylvestris L.) using FTIR spectroscopy.

spectrum of a material to be obtained simply by pressing the sample against a transparent crystal, commonly diamond. The infrared light passes through the crystal into the sample where energy is absorbed by the sample, and the light is reflected back into the crystal to generate a spectrum. A Thermo Scientific™ Nicolet™ iS5 FTIR In Fourier transform infrared spectrometers, a background measurement is casually made before the sample measurement. However, if this measurement will be made carefully, you can obtain more satisfactory measurements. Now select the 'Measurement' tab and check the box beside 'Display Background (K)' (Fig. 1) to carry out a background measurement.
