Located in the spectral range between 3 and 30 microns, mid-IR can perform qualitative and quantitative measurements on organic and inorganic molecules within different matrice (gas, liquid, or solid) ...

An ultimate goal in modern chemistry ... FTIR, an optical technique that combines scattering-type scanning near-field optical microscopy (s-SNOM) and Fourier transform infrared (FTIR) spectroscopy.
