The far-infrared, approximately 400-10 cm-1 (1000–30 μm), lying adjacent to the microwave region, has low energy and may be used for rotational spectroscopy. 3. The absorption bands recorded with suitable IR spectrometers or NIR spectrometers are used for structural elucidation of unknown or, for the identification of (mostly) organic compounds - after the analysis and interpretation of spectral data. Science and Fun, SDBS... is an integrated spectral database system for organic compounds. Fourier Transform Infrared Spectroscopy (short FT-IR) is one of the techniques that are used today for mea-suring the intensity of infrared radiation as a function of frequency or wavelength. Theory The infrared portion of the electromagnetic spectrum is divided into three regions; the near-, mid- and far- infrared, named for their relation to the visible spectrum.
