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
Proton second moment and spin-lattice relaxation times T and T in solid anhydrous b-estradiol are measured as a 1 1 r function of temperature. The results show that the C reorientation of the single methyl group provides the mechanism 3 dominating relaxation at low temperatures and reveal the existe
