Anotations

Scope note:

Method of obtaining infrared spectra absorption, emission, photoconductivity or Raman scattering solids, liquids or gas by first collecting an interferogram of a sample signal using an interferometer, and then performing a Fourier Transform (FT) on the interferogram to obtain the spectrum.
