Spectroscopy In the past, IR spectra had to be aquired one wavelength at a time, which took a long time. Today quick spectra is due to the the Fourier Transfer Algorithm allows us to scan all frequencies at once None of these light is faster today that it used to be absence of broad spectrum of wavelenth the Fourier Transfer Algorithm allows us to scan all frequencies at once None of these light is faster today that it used to be absence of broad spectrum of wavelenth ANSWER DOWNLOAD EXAMIANS APP
