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.

  • Nice !

    

  • hi i had one question .Can FTIR be used for samples like polycarbonate or other samples which are not transparent to IR? Is there any related technique for such materials?

  • Thanks so much. It really helps. More Lab experiment videos plz

  • good work! thanks
