By learning where characteristic functional-group absorptions occur, it’s possible to get structural information from IR spectra. Table 12.1 lists the characteristic IR bands of some common functional groups.
This article will provide a table containing the IR spectrum frequency values and the molecules they represent.

Table of Characteristic IR Absorptions. Infrared Spectroscopy –Analytical chemistry laboratory, ICT Prague. THEORY. An important tool of the analytic and organic chemists is Infrared (IR) Spectroscopy. IR spectra are acquired on a special instrument, called an IR spectrometer.
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.
