Özet
In this study, solvent proton spin-lattice (T-1) and spin-spin (T-2) relaxation times in agar Solutions vs. increasing agar concentrations were measured by a FT-NMR. Each of 1/T-1 and 1/T-2 rates was linearly proportional to the agar concentration. The relations between the relaxation rates and agar concentrations correspond to the formulas representing the fast chemical exchange of water protons between free water and water bound to agar. The present results suggest that the ratio of relaxation rates in bound phase (T-2b/T-1b) is equal to the ratio of the slopes in the relations (K-2/K-1), and the tau can be calculated from the equality of these ratios.
