Dynamic-angle spinning and double rotation of quadrupolar nuclei

Double rotation NMR studies of zeolites and aluminophosphate molecular sieves

“…General results using the latter method are discussed here. For a more detailed treatment the aforementioned references, as well as other, more recent.analyses [172,176,177] are recommended.…”

“…A general expansion upon the discussion presented here can be found in ref. [172]. RlX_min Equation A.8 contain the spatial parts of the interactions.…”

“…After calculation of the matrix elements and applying the selection rules for the various indices [172], the central transition resonance is finally given by:…”

Scalar operators in solid-state NMR

“…After to label a vertex, P for pentagon, T for triangle, and E for edge of the symmetry geometry, and C to label center and Latin letters in the indices to distinguish different centers transfonnation of the amplitude of the DAS echo, a high resolution spectrum can be obtained. The details about the DAS experiment [80] will be described in next section and the physical insight about I?AS also will be theoretically thoroughly treated in the final section of this chapter.…”
