WebElectromagnetic Spectrum. FTIR spectroscopy takes advantage of how IR light changes the dipole moments in molecules (Fig. 2) that correspond to a specific vibrational energy. … FTIR can be used in all applications where a dispersive spectrometer was used in the past (see external links). In addition, the improved sensitivity and speed have opened up new areas of application. Spectra can be measured in situations where very little energy reaches the detector and scan rates can exceed 50 spectra a second. Fourier transform infrared spectroscopy is used in geology, chemistry, materials and biology research fields.
