The following table lists infrared spectroscopy absorptions by frequency regions.

IR Tables, UCSC Table 1. Characteristic IR Absorption Peaks of Functional Groups*

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. [1][2] In physical and analytical chemistry, infrared spectroscopy (IR spectroscopy) is a technique used to identify ...

From there, a data table of approximate frequencies for different types of bonds has been created to use to help IR spectrum analysis. Table of Common IR Absorptions. Note: strong, medium, weak refers to the length of the peak (in the y axis direction).

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

The carbonyl stretching absorption is one of the strongest IR absorptions, and is very useful in structure determination as one can determine both the number of carbonyl groups (assuming …
