文摘
Different susceptibility NMR line shifts can be induced in distinct liquid solutions by dissolving different concentrations of complexes of paramagnetic lanthanide Ln3+ ions. We show how these solutions, put in capillaries, can be simultaneously studied with a standard high-resolution spectrometer. After theoretical justification the method is illustrated by an investigation of the effects of H/D substitution on self-diffusion in heavy water. Non-Stokesian effects are observed.
