High-resolution NMR spectra of spin-1/2 nuclei, particularly Sn-119 and insolid tin(II) phosphite, SnHPO3,and tin(II) phosphate, SnHPO4, are presented. The results are discussed in relation to the crystal structures. Spinning sideband analysis has be... Read More about Solid-state NMR studies of some tin(II) compounds.

NMR crystallography: the use of chemical shifts (2004)
Journal Article
Harris, R. (2004). NMR crystallography: the use of chemical shifts. Solid State Sciences, 6(10), 1025-1037. https://doi.org/10.1016/j.solidstatesciences.2004.03.040

Measurements of chemical shifts obtained from magic-angle spinning NMR spectra (together with quantum mechanical computations of shielding) can provide valuable information on crystallography. Examples are given of the determination of crystallograph... Read More about NMR crystallography: the use of chemical shifts.

Solid-state Ag-109 CP/MAS NMR spectroscopy of some diammine silver(I) complexes (2004)
Journal Article

2D and 3D DOSY methods for studying mixtures of oligomeric dimethylsiloxanes (2004)
Journal Article

Diffusion-ordered spectroscopy (DOSY) is a powerful method for the NMR analysis of many types of mixture without the need for physical separation, and requires only relatively standard spectrometer hardware. The principal requirements for high resolu... Read More about 2D and 3D DOSY methods for studying mixtures of oligomeric dimethylsiloxanes.

Variable temperature studies of a polymorphic system comprising two pairs of enantiotropically related forms: S,S -ethambutol dihydrochloride (2004)
Journal Article

Of the four known polymorphs of [S,S] -ethambutol dihydrochloride, two transform in an enantiotropic single-crystal-to-single-crystaI phase transformation from Form II to Form I on heating. The crystal structures of these two forms have been solved a...

NMR studies of P-31, H-1 spin pairs in solid tin(II) phosphite and tin(II) hydrogen phosphate (2004)
Journal Article

We show how the spin dynamics in isolated spin systems presents both opportunities and complications, using the H-1, P-31 pair encountered in solid SnHPO3 and SnHPO4. Transient oscillations observed in the build-up of P-31 magnetization, during cross... Read More about NMR studies of P-31, H-1 spin pairs in solid tin(II) phosphite and tin(II) hydrogen phosphate.

Application of the through-bond correlation NMR experiment to the characterization of crystalline and disordered phosphates (2004)
Journal Article

Through-bond correlation NMR experiments have been used to characterize the structure of MP2O7 crystalline compounds and disordered phosphates. For MP2O7 materials, the refocused INADEQUATE experiment allows discrimination between the possible space...
