IR Spectroscopy

Information resources on infrared spectroscopy.

IR spectroscopy (also: infra-red spectroscopy) is the name for an optically-physical routine process for the recording of absorption spectra of chemical substances in the near (NIR), mid (MIR) and far (FIR) infrared spectrum. IR spectroscopy is a spectroscopic technique to identify chemical compunds and to investigate sample composition.

The absorption bands recorded with suitable IR spectrometers or NIR spectrometers are used for structural elucidation of unknown or, for the identification of (mostly) organic compounds - after the analysis and interpretation of spectral data.

Below you will find online available information resources on infrared spectroscopy.
