摘要：

The proton magnetic resonance (PMR) spin-lattice and spin-spin relaxation times (T1 and T2) were measured in aqueous solutions of glycine and L-proline as a function of solute concentrations and at a temperature of 32-degrees-C. The relaxation times were measured using Bruker PC 120 NMR process analyser. The relaxation times were found to decrease with increase of solute concentrations. The results are interpreted on the basis of flickering cluster model and hydrogen bond formation between solute and solvent molecules.
