WebbQuestion: Consider the following statements as they apply to infrared spectroscopy. Decide if each is true or false. Infrared spectroscopy is most commonly used for making qualitative determinations. In dispersive infrared spectroscopy, an interferogram is collected and then mathematically converted to a frequency domain spectrum.

WebbThe usefulness of infrared spectroscopy arises because different chemical structures (molecules) produce different spectral fingerprints. So, what is FTIR? The Fourier Transform converts the detector output to an interpretable spectrum. The FTIR generates spectra with patterns that provide structural insights.
