THE DETERMINATION OF LONGITUDINAL RELAXATION RATE OF Fe(H_2O)_6^(3+) COMPLEX UNDER FAST EXCHANGE SYSTEM OF TWO SITES

通过对水与水合Fe3+配合物的二位快交换体系的纵向弛豫速率的测定 ,得出了在本实验条件下磁化效应与权重平均表达方式的相似性 ,进而得出了水合Fe3+配合物纵向弛豫速率 .有助于研究水溶液中的离子配合物 .

Through the study on longitudinal relaxation determination of the two site fast exchange system of H\-2O and Fe(H\-2O)\+\{3+\}\-6, it was found that under the condition of the experiment, the express forms of the observed longitudinal rates of weight average and relaxivity of Fe\+\{3+\} were the same, then the relaxation rate of Fe(H\-2O)\+\{3+\}\-6 was obtained. It would be helpful in studying the complexes of ions and H\-2O in water solution. \;
