WebDec 1, 2024 · In the Czjzek model of disorder in a solid, the electric field gradient tensor elements are drawn from a Gaussian distribution. The resulting NMR spectral lineshape … WebAs with the case with Czjzek distribution, to generate a probability distribution of the extended Czjzek distribution, we need to define a grid system over which the distribution …
WebAug 10, 2016 · Here we show how to transform to a new set of coordinates that decreases the distortion inherent in Czjzek’s representation. These new coordinates allow one to express the joint PDF for random distributions of defects in a form reasonably approximated by the product of two independent marginal distributions. 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.
