Investigations on the dynamical and structural properties of electroly
te solutions based on NMR relaxation methods are reported. Using selec
ted examples of electrolytes in pure solvents, the behaviour of the so
lvent molecules in the first coordination sphere of ions is highlighte
d. Moreover, by splitting intra- and inter-molecular contributions to
the relaxation for some electrolytes in DMSO, the influence of the sal
ts on the reorientational and translational properties of the solvent
molecules is shown. Finally, NMR relaxation by quadrupolar interaction
s to probe the preferential solvation of ionic species in binary solve
nt mixtures is reported.
