Description of the method
In IR spectroscopy (infrared spectroscopy), molecules are irradiated with infrared light, which excites them into characteristic vibrations. The resulting absorption spectrum provides a ‘molecular fingerprint’ that allows conclusions to be drawn about the chemical structure.
Examples of applications
- Structural elucidation, identification of functional groups
- Verification of synthesised compounds, purity control.
- Determination of fat, protein and water content
- Identification of contaminants
