A pulsed Fourier-transform spectrometer does not employ transmittance techniques . In the most general description of pulsed FT spectrometry, a sample is exposed to an energizing event which causes a periodic response. The frequency of the periodic response, as governed by the field conditions in the spectrometer, is indicative of the measured properties of the analyte. In magnetic spectroscopy (EPR, NMR), a microwave pulse (EPR) or a radio frequency pulse (NM… WebHow to do this you have to consult the FTIR instrument designers.
