Proton dynamics in solid dopamine and noradrenaline hydrochloride.
Proton spin-lattice relaxation times (T1) have been measured as a function of temperature for the following catecholamines: dopamine hydrochloride and adrenaline hydrochloride. For both substances a single symmetric minimum of T1 is observed which can be explained as a result of NH3 (dopamine) and CH3 (adrenaline) reorientation around the three-fold axis of the C-N bond. The activation parameters have been determined.
