The dynamics of oxygen motion in ZrW2O8 have been characterized using O-17 solid-state NMR. Rates of dynamic exchange have been extracted from magnetization transfer experiments over a temperature range of 40 to 226 degrees C, and distinct values for...

We have characterised the stable polymorphic forms of two drug molecules, indomethacin (1) and nifedipine (2) by C-13 CPMAS NMR and the resonances have been assigned. The signal for the C-Cl carbon of indomethacin has been studied as a function of ap... Read More about Characterisation of indomethacin and nifedipine using variable-temperature solid-state NMR.

Carbon-13 NMR spectra of the stable polymorphs of solid bambuterol hydrochloride (BHC) and terbutaline sulfate (TBS) are reported and the resonances assigned with the aid of solution-state spectra. A protocol is presented for quantification of BHC in... Read More about Quantification of bambuterol hydrochloride in a formulated product using solid-state NMR.

This paper describes synthetic routes to produce highly O-17 enriched samples of the negative thermal expansion materials ZrW2O8 and ZrMo2O8. In the case of ZrW2O8 enriched samples can be produced either via enriched Zr-17 O-2 and (WO3)-O-17, which h... Read More about Synthesis and NMR studies of O-17 enriched AM(2)O(8) phases.
