## Spin-lattice relaxation times T, and T,, as well as 'H NMR spectra have been employed to study the dynamics of the glass-forming di-isobutyl phthalate in the temperature range extending from 100 K, through the glass transition temperature Ts, up to 340 K. Below 2" NMR relaxation is governed by
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
