摘要
The proton spin-lattice relaxation time T-1 and the nuclear magnetic resonance second moment were used to study the molecular dynamics of 1,2-O-(1-ethylpropylidene)-alpha-D-glucofuranose, a new low-molecular-weight organogelator, in the temperature range of 85-308 K. The observed T-1 minima were attributed to the motion of methyl groups. The experimental data were interpreted in terms of Haupt's theory assuming the tunneling-assisted relaxation process.
