WebThe IR spectra of alcohols and phenols give characteristic broad O–H stretching absorptions in the region 3600–3200 cm−1. These absorptions are broader than N–H absorptions but are not as broad as the O–H absorption of a carboxylic acid. The exact position of the absorption depends on the extent of hydrogen bonding in the sample.
