1.1 Limitations of infrared spectromicroscopy
Spectroscopy involves studying the interaction between an electromagnetic wave (in the context of this article) and matter, by observing excitation or de-excitation phenomena, depending on the energy or frequency of the wave. In the infrared range, the study of electromagnetic wave absorption enables us to probe the molecular vibrations of matter. The 4,000-500 cm frequency range -1 (2.5 to 20 microns), known as "mid-infrared", is of particular interest, as it contains all the vibrational bands of organic compounds. Infrared spectroscopy is therefore a highly effective tool for the chemical identification of matter. Applications cover many fields: biomedical (determination of tissue composition,...
