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).What are the functional groups in IR?

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.
