Abstract

207Pb NMR spectra of mixed crystals of anhydrous lead and strontium nitrate show up to 13 lines, arising from lead ions with 0-12 Pb2+ nearest-neighbor cations replaced by Sr2-. The shifted lines are further split by the multiplicity of inequivalent nearest-neighbor replacements. The average shift per Sr2+ ion is 21.8 ppm. Similar but somewhat smaller effects are seen in [Pb,Ba](NO3)2 mixed crystals. The intensities of the resonances can be fit to Monte Carlo models of Pb2- and Sr2+ ion distributions and are consistent with like nearest-neighbor pairs being 120 J/mol lower in energy than unlike pairs.
