✦ Synopsis
The proton dynamics in phenylephrine hydrochloride, isoprenaline hydrochloride and norephedrine hydrochloride have been monitored by measuring the temperature dependence of the 'H spin-lattice relaxation times. The results are interpreted as due to C,-hindered reorientation of the NH, and CH, groups. The activation parameters have been determined.

Molecular motions of polycrystalline cellobiose have been investigated by measuring proton spin-lattice relaxation times, T1 and T1rho, and the second moment, M2, in both protonated and D2O exchanged forms over the temperature range 120-380 K. T1 relaxation is dominated by the motions of hydroxyl gr
Spin-lattice relaxation times T 1 and T 1d as well as NMR second moment were employed to study the molecular dynamics of riboflavin (vitamin B 2 ) in the temperature range 55-350 K. The broad and flat T 1 minimum observed at low temperatures is attributed to the motion of two nonequivalent methyl gr
