摘要：

The bulk magnetic susceptibility (BMS) shifts of H-1 NMR resonance signals for inert reference compounds caused by the addition of paramagnetic lanthanide(IH) compounds were exploited in order to determine lanthanide(III) concentrations in solution. The BMS shifts of an inert reference compound in the samples were measured by comparing the chemical shifts with those of an external reference. The concentration values obtained were in good agreement with results acquired from inductively coupled plasma analysis. Copyright (C) 2001 John Wiley & Sons, Ltd.
