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.
Table of Characteristic IR Absorptions. You can download this chart as a printable acrobat pdf file.
Infrared spectroscopy is the study of the interaction of infrared light with matter. The fundamental measurement obtained in infrared spectroscopy is an infrared spectrum, which is a plot of measured infrared intensity versus wavelength (or frequency) of light.
This article will provide a table containing IR spectrum absorbtion frequency values and what they represent.
Infrared Tables (short summary of common absorption frequencies) The values given in the tables that follow are typical values. Specific bands may fall over a range of wavenumbers, cm-1. Specific substituents may cause variations in absorption frequencies.
