WebFeb 3, 2015 · In a matter of seconds, the FTIR instrument produces a graph called a spectrum. The peaks in the spectrum represent chemical bonds between two atoms or groups of atoms in a molecule. Since each material has a unique combination of atoms, no two compounds produce identical spectra. 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 …
