| Abstract: | An alternative explanation of the behavior of proton magnetic resonance chemical shifts of the water proton in aqueous tetraalkylammonium salt solutions is presented. It involves independent ion-solvent interactions and rapid exchange on the NMR time scale with the bulk water. Our explanation fits the known data and clearly shows why the observed chemical shift is linear with molality at low concentrations. |
