WebWhat is FT-IR? FT-IR stands for Fourier Transform InfraRed, the preferred method of infrared spectroscopy. In infrared spectroscopy, IR radiation is passed through a sample. Some of the infrared radiation is absorbed by the sample and some of it is passed through (transmitted). The resulting spectrum represents the molecular absorption and ... WebSep 16, 2024 · In FTIR spectroscopy, an interference wave is synthesized from two beams separated by a beam splitter, the detected interference waveform (interferogram) is Fourier-transformed, and a spectrum is obtained by separating each wavenumber. Fig. 6 shows an overview of the conversion of an interferogram for bichromatic light into an IR spectrum.
WebTo use an IR spectrum table, first find the frequency or compound in the first column, depending on which type of chart you are using. Then find the corresponding values for absorption, appearance and other attributes. The value for absorption is usually in cm -1. Note that not all frequencies have a related compound.
