NMR relaxation study of Li+–Ni2+ interaction in aqueous solution

Abstract
The NMR relaxation of 7Li+ due to Ni2+ in aqueous solution as a function of magnetic field strength is experimentally determined and is calculated on tha basis of certain models for the ionic interactions. The results can be used to eliminate some models which are consistent with the osmotic coefficient data for aqueous LiCl, NiCl2, and their mixtures.
