• How do you find the functional group of an IR spectrum?

  The other common functional groups have bands between the fingerprint region and the C-H stretching absorptions. Don't get too distracted by the mess in the fingerprint region. Instead, look primarily in the important places (between 1,500 and 2,800 cm^–1, and above 3,000 cm^–1).

  1Is there a broad, rounded peak in the region around 3400-3200 cm-1 ? That's where hydroxyl groups (OH) appear.2Is there a sharp, strong peak in the region around 1850-1630 cm-1 ? That's where carbonyl groups (C=O) show up.
