Molecular Dynamics in a New Solid Glucofuranose-Based Low-Molecular-Weight Organogelator as Studied by 1H NMR

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)-α-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.
