Relaxation characteristics of Na+ and K+ water clusters were studied by 17O NMR spectroscopy. The influence of viscosity p and pH of solution was taken into account; for both electrolytes in the concentration range 10-5-4 M, spin-spin relaxation times are greater than those for pure water. For K+ clusters, maxima of the concentration dependence of 17O spin-spin relaxation time have been found.
