Figure Lengend Snippet: Fig. 5 1/T1 NMRD profiles of Gd-1/dimer 4 (), Gd-2/dimer 4 (■) and Gd-3/dimer 4 (★) adducts, as determined at pH = 7 and 298 K. Solid curves through data points were calculated with parameters reported in Table 1. The fitting procedure was been performed by assuming: q (number of coordinated water molecules) = 1; r (distance between the Gd(III) ion and the protons of the coordinated water molecule) = 3.1 A˚ ; a (distance between the Gd(III) ion and the outer-sphere water proton nuclei = 3.8 A˚ ; D (solute-solvent diffusion coefficient) = 2.247 ¥ 10-5 cm2 s-1; tM (exchange lifetime of the inner-sphere water molecule) was fixed to the value previously obtained for the free complexes (200 ns).
