title: Proton dynamics in solid noradrenaline hydrochloride.
abstract: The temperature dependencies of the proton spin-lattice relaxation times and second moment of the 1H nuclear magnetic resonance line have been measured for noradrenaline hydrochloride. Two symmetric minima of T1 are observed. They can be explained in terms of reorientation of the ammonium groups and proton transfer in the hydrogen bond. The activation parameters have been determined.
