Fourier Transform Infrared Spectroscopy (FTIR) is an extremely useful form of infrared spectroscopy that utilizes an interferogram to collect all of the frequencies to be collected simultaneously. This can be used easily for substance identification by comparing the resultant spectra with a library of known substances. The frequencies are initially passed through an interferogram, which then undergoes a Fourier transformation that combines to produce a spectrum. This spectrum is essentially identical to a normal infrared spectrum for the same compound, except it is produced much faster.
