WebMar 22, 2024 · mass spectrometry, also called mass spectroscopy, analytic technique by which chemical substances are identified by the sorting of gaseous ions in electric and magnetic fields according to their mass-to-charge ratios. The instruments used in such studies are called mass spectrometers and mass spectrographs, and they operate on the … WebTo use an IR spectrum table, first find the frequency or compound in the first column, depending on which type of chart you are using. Then find the corresponding values for absorption, appearance and other attributes. The value for absorption is usually in cm -1. Note that not all frequencies have a related compound.
