Proton nuclear magnetic resonance spectroscopy is one of the most commonly used spectral methods for the characterization of organic compounds. It provides proton information on chemical shifts, integral areas, and coupling splits of organic compounds. The common active hydrogen is a hydrogen atom covalently linked to oxygen, nitrogen, or sulfur. There is rapid active proton exchange which makes significant difference from other carbon-linked hydrogen. Under different conditions, the chemical shift of active hydrogen is not fixed, the peak shape is variable and the coupling split is complicated. In order to cultivate students' practical ability on observing, analyzing and structure characterizing, active hydrogen identification by proton nuclear magnetic resonance spectroscopy was discussed in the article.

Key words: Proton nuclear magnetic resonance spectroscopy, Active hydrogen
