Abstract: Through the study on longitudinal relaxation determination of the two-site fast exchange system of H2O and Fe(H2O)63+, it was found that under the condition of the experiment, the express forms of the observed longitudinal rates of weight average and relaxivity of Fe3+ were the same, then the relaxation rate of Fe(H2O)63+ was obtained. It would be helpful in studying the complexes of ions and H2O in water solution.

Key words: Two-site fast exchange, Longitudinal relaxation, Complex of ions
