Example Question #1 : Infrared (Ir) Spectroscopy
An IR spectroscopy reading of a compound shows a large absorption at . What is the identity of this compound?
Compounds with an alcohol group show absorptions in an IR sprectrum from through . Therefore an absorption of would correspond to an alcohol. Amide groups show absorptions from through . Amine groups show absorptions from through , through , through and through (aromatic amines). Carbonyl compounds such as aldehydes show strong absorptions in the IR spectrum at through .
