The distributions of both the quadrupolar and the isotopic chemical shift interactions are shown to give multiple-quantum MAS spectra that remain tilted after shearing. For both types of distribution, the theoretical slopes, formed by the resulting distribution of the centers of gravity of the signa
In order to check the efficiency of high-power 1 H decoupling when used with the two-dimensional multiple-quantum MAS method recently proposed to obtain isotropic spectra from quadrupolar nuclei, we applied this new technique to 23 Na NMR for a hydrous layered silicate compound, makatite, with and w
