How does internal motion influence the relaxation of the water protons in Ln(super 111)DOTA-like complexes?

The influence of internal motion on the relaxation of the water protons in Ln(super 111)DOTA-like complexes is detailed. The bound water internal motion also affects macromolecular complexes, but when the final effect when combined with the local motion of the chelating group should be generally less than what is observed for the monomeric species.
