Rotational molecular motion and solvation of Na⁺ and Cs⁺ in water-dimethylacetamide. A nuclear magnetic relaxation study

Nuclear magnetic relaxation by intra- and intermolecular quadrupoleelectric field gradient interaction has been used for the study of the systems DMA-water-NaI and DMA-water-CsI at 25°C.¹⁴N relaxation of DMA and²

Separation of local asymmetry and selective solvation effects using the quadrupole relaxation of the²³Na⁺ and⁸⁷Rb⁺ ions in acetonitrile-water mixtures

Nuclear magnetic relaxation rates of²³Na⁺,⁸⁷Rb⁺, and¹⁴N in acetonitrile-water mixtures have been measured over the complete mixture range. The interaction of the quadrupole moment of ionic nuclei with electric fi...
