Fourier Transform Infrared (FTIR) Spectroscopy
This spectroscopic technique uses a Michelson interferometer to create an interferogram. An infrared source with many wavelengths is passed through a sample, which creates interference patterns as different wavelengths are differentially absorbed. The mathematical technique of Fourier transform is used to convert the raw signal into a recognizable absorption spectra, similar to those produced by a UV/VIS spectrometer.
