An infrared spectroscopy correlation table (or table of infrared absorption frequencies) is a list of absorption peaks and frequencies, typically reported in wavenumber, for common types of molecular bonds and functional groups.

The following table lists infrared spectroscopy absorptions by frequency regions.

You can search for FTIR functional groups by peak position, group, or class quickly from the table.

Characteristic IR Absorption Peaks of Functional Groups* * Abbreviations: s = strong; m = medium; w = weak; br = broad; sat. = saturated; conj. = conjugated ** Alcohols, Esters, Carboxylic Acids, and Anhydrides also absorb in the fingerprint region due to …

FT-IR Spectroscopy; IR Absorption Frequencies ; Typical IR Absorption Frequencies For Common Functional Groups. Bond Functional Group Frequency in cm −1 (Intensity*) C–H: Alkane: 3000–2850 (s) –CH 3: 1450 and 1375 (m)

Detailed information about the infrared absorptions observed for various bonded atoms and groups is usually presented in tabular form. The following table provides a collection of such data for the most common functional groups.

Nov 23, 2016 · We can observe and measure this “singing” of bonds by applying IR radiation to a sample and measuring the frequencies at which the radiation is absorbed. The result is a technique known as Infrared Spectroscopy, which is a useful and quick tool for identifying the bonds present in a given molecule.

Jul 16, 2018 · The peaks, which are also called absorbance bands, correspond with the various vibrations of the sample’s atoms when it’s exposed to the infrared region of the electromagnetic spectrum. For mid-range IR, the wave number on the infrared spectrum is …

Fourier transform infrared spectroscopy (FTIR) [1] is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gas. An FTIR spectrometer simultaneously collects high-resolution spectral data over a wide spectral range.

A Fourier transform infrared (FTIR) spectrometer is an ideal tool for the identification of unknown organic and inorganic samples whether they exist in the form of a gas, liquid or a solid.
