New developments in NMR of simple electrolyte solutions

Oxygen-17 NMR spectroscopy: Basic principles and applications (Part I)

“…In spite of the fact that these calculations are strictly valid only for the gas phase, they can be useful for the discussion of experimental data obtained in solution [366][367][368][369]. Fujikura and Rode [365] concluded that changes of d( 17 O) and d( 13 C) are influenced mainly by changes in the p-electron populations induced by the cations.…”

Oxygen-17 NMR spectroscopy: Basic principles and applications (part II)

“…Nevertheless the use of isotopic substitution deserves special attention, since it allows one to ''switch on and off" dipole-dipole interactions of solute nuclei with those of the solvent molecules [369,734]. In this way the interaction of interest can be filtered out from the rest of the relaxation contribution.…”

A Study of Solvation-Shell Symmetry in Electrolyte Solutions Using Quadrupolar NMR Relaxation of the Nuclei of Monoatomic Ions

“…To explain the shape of the curves it is necessary to take into account several effects. The data of previous works (3)(4)(5)(6)(7)(8)(9)(10)(19)(20)(21) show that the monoatomic ions possess symmetrical hydration shells in aqueous solutions. It is well known In the case of fast exchange of the ions among all possible to viscosity variations can be predicted from the relaxation times, T s 1 , of the solvent molecule nuclei, 2 H and 17 O.…”
