The method of Fourier transform spectroscopy can also be used for absorption spectroscopy. The primary example is  FTIR Spectroscopy , a common technique in chemistry.rom Wikipedia, the free encyclopedia. Fourier transform spectroscopy is a measurement technique whereby spectra are collected based on measurements of the coherence of a radiative source, using time-domain or space-domain measurements of the electromagnetic radiation or other type of radiation.
