The Czjzek model provides an analytical expression for the joint distribution of the NMR quadrupolar parameters upsilon(Q) and eta from which a lineshape can be predicted.

Even without calculations, these NMR results point toward P 6 3 / mmc (194) as the correct space group, since there is no experimental evidence of the second Mg 2+ site required by P 6 3mc (186). WebA Czjzek model revealed the chemical shift and quadrupolar coupling distributions of the three surface environments. These showed little difference between pristine γ-alumina and its BaO-modified counterpart with only a reduction in the intensity of the AlO 5 signal and a concomitant increase for AlO 4. diathesis stress model examples

"WebThis conclusion, however, is based on the simplifying assumption that the 25Mg spectrum comprises a Czjzek distribution centered at a single isotropic chemical shift value and stands in contrast to the results of recent isotope-selective neutron diffraction studies which give an average Mg-O coordination number of 4.4-4.5 for both glasses.
