www.chemie-biologie.uni-siegen.deFourier-transform spectroscopy. IR-Spectroscopy “Classical” (grating, prism) IR spectroscopy has been replaced by the much faster FTIR spectroscopy. In the case of the “classical” (i.e. non FT) infrared spectroscopy the different wavelengths had to be measured successively. In the

xuv.scs.illinois.eduAn FTIR interferogram converts wavelength into mirror position (i.e. energy into time). The central peak is at the ZPD position ("Zero Path Difference") where the maximum amount of light passes through the interferometer to the detector. FTIR Interferogram The interferogram is then fast Fourier transformed (FFT) back into the

The computer can perform the Fourier transformation calculation and present an infrared spectrum, which plots adsorbance (or transmittance) versus wavenumber. When an interferogram is Fourier transformed, a single beam spectrum is generated. A single
