This article will provide a table containing IR spectrum absorbtion frequency values and what they represent.

Typical IR Absorption Frequencies For Common Functional Groups ... s = strong; m = medium; w = weak

Table of IR Absorptions ... All figures are for the typical case only -- signal positions and intensities may vary depending on the particular bond environment.

IR Spectrum Chart: An IR spectrum chart graphically represents the IR spectrum of a compound, showing the absorption frequency on the x-axis and the intensity of the absorption on the y …

A comprehensive IR table systematically lists the typical infrared absorption frequencies for various functional groups, enabling precise identification of molecular structures in samples.

If you are looking up the absorption of a particular compound class, use this IR spectrum chart. If you already know the frequency, use the IR frequency table above.
