|a The practicality of obtaining liquid- and solid-state 207 Pb nuclear magnetic resonance (NMR) spectra with a low permanent-field magnet is investigated. Obtaining 207 Pb NMR spectra of salts in solution is shown to be viable for samples as dilute as 0.05 M. The concentration dependence of the 207 Pb chemical shifts for lead nitrate was investigated; the results are comparable with those obtained with high-field instruments. Likewise, the isotope effect of substituting D2 O for H2 O as the solvent was investigated and found to be comparable with those reported previously. Obtaining solid-state 207 Pb NMR spectra is challenging, but we demonstrate the ability to obtain such spectra for three unique solid samples. An axially symmetric 207 Pb powder pattern for lead nitrate and the powder pattern expected for lead chloride reveal linewidths dominated by shielding anisotropy, while 207 Pb-35/37 Cl J-coupling dominates in the methylammonium lead chloride perovskite material. Finally, recent innovations and the future potential of the instruments are considered
