Infrared absorption spectroscopy [2] is a linear absorption technique in which intrinsic vibrational modes of the molecules are utilized to identify them [3]. ... The IR absorption spectra display absorption lines in these regions depicting vibrational transitions of molecules to register the presence of the molecules.
What is the IR spectrum range?
The typical IR absorption range for covalent bonds is 600 - 4000 cm-1. The graph shows the regions of the spectrum where the following types of bonds normally absorb. For example a sharp band around 2200-2400 cm-1 would indicate the possible presence of a C-N or a C-C triple bond.
What causes the absorption bands in an IR spectrum?
The H-Cl stretch of hydrogen chloride and the asymmetric stretch of CO2 are examples of infrared active vibrations. Infrared active vibrations cause the bands seen in an infrared spectrum.
