Fourier transform IR spectroscopy (FT-IR): An infrared spectroscopy technique in which the analyte is exposed an infrared photon beam containing many photon wavelengths, and the data recorded. The process is repeated multiple times, each with a different set of infrared photon wavelengths. The resulting data is combined and treated with a mathematical process called a Fourier transform to produce the infrared spectrum.
