Sensitive information: Hydrogen bonds stabilize protein structures and are critical for many chemical and biological phenomena. NMR studies found that the one-bond 1H–15N scalar coupling constant is increased by up to 1.6 Hz when a hydrogen bond is formed. These coupling constants therefore provide a sensitive tool for studying protein structure.
