This website allows to predict and interactively analyze IR spectra.
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.
Table of Characteristic IR Absorptions. You can download this chart as a printable acrobat pdf file. m=medium, w=weak, s=strong, n=narrow, b=broad, sh=sharp.
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.
8 maj 2024 · Infrared spectra contain peak position, height, and width information. Peak positions are determined the force constants and reduced masses of a vibrating functional group. Peak heights are determined by Beer’s Law, including the absorptivity, pathlength, and concentration.
This article will provide a table containing the IR spectrum frequency values and the molecules they represent.
The lookup tool below is designed to provide insight into unknown peaks in your IR spectrum. It contains many common functional groups along with their characteristic IR absorption frequencies (in wavenumbers).
