| Abstract: | The RF losses in NMR experiments on ionic solutions have been investigated by multi-NMR. The change of π/2 pulse length (PW)90 for23Na,35Cl,2D,17O and1H nuclei in NaCl/D2O solutions has been systematically studied. Quantitative relation between (PW)90 values and the sample specific conductivity σ has been established. The increase in (PW)90 values has been experimentally correlated to the reduction of the signal-to-noise ratio through17O measurements. |
