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.

8 maj 2024 · Infrared (IR) spectra contain three pieces of information: peak positions; peak heights; and peak widths. All these pieces of information tell us about the structure, concentration, and condition of molecules in a sample.
Peaks are typically described by their intensity (strong, medium or weak) and by their peak width (sharp and broad). The table below shows sharp and broad peaks present from the infra-red spectrum above.
The following table lists infrared spectroscopy absorptions by frequency regions.
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.
16 mar 2023 · In this section we shall learn how to recognize the presence of characteristic IR absorption peaks that result from vibrations of alkyl and functional groups. Part I: Infrared Spectroscopy: An Instrumental Method for Detecting Functional Groups
The peaks on an infra-red spectrum can be used to identify the functional groups present in a molecule as each bond absorbs a specific frequency of IR radiation. A peak can be compared with known values in the data book to identify the bond.
