Relaxation of solvent protons by paramagnetic ions and its dependence on magnetic field and chemical environment: implications for NMR imaging.
TL;DR: In this article, the main features of relaxation of solvent protons in the presence of solute paramagnetic ions, as hydrated aquoions and complexed with protein, are presented, with attention to those ions most relevant to in vivo studies.

Nuclear magnetic relaxation dispersion in protein solutions: V. Bovine erythrocyte superoxide dismutase
TL;DR: It is concluded that there is at least one rapidly exchanging water molecule (exchange time τM in the range 4·10−6 to 10−8 s) on each of the two Cu2+ per protein molecule, and speculate that the water binding sites on the Cu2+, are similarly accessible to the superoxide anion and are the loci for the catalytic activity of the enzyme.
Journal ArticleDOI
Relaxation of water protons in the intra- and extracellular regions of blood containing Gd(DTPA).
TL;DR: It is shown that Gd is in the extracellular space only and is present as rotationally mobile Gd(DTPA), uncomplexed with protein or blood cells; and that the water protons exchange rapidly between the intra‐ and Extracellular regions.
