4.1 Gas spectroscopy
The mid-infrared spectral region, more specifically between 400 and 4,000 cm –1 (2.5 to 25 μm), contains the absorption lines associated with transitions between the rotational and vibrational levels of molecules. These absorption lines are known as molecular fingerprints, since their characteristic frequencies enable molecules to be identified very precisely. By precisely measuring the absorption value, it is possible to trace...
