Dynamic effects in MAS and MQMAS NMR spectra of half-integer quadrupolar nuclei: Calculations and an application to the double perovskite cryolite

A description is provided about the dynamic effects of the multisided MAS (magic angle spinning) and MQMAS (multiple quantum magic angle spinning) and also relates them to evaluate the vast processes that take place in the double perovskite cryolite. Finally, the evaluation shows that synthetic cryolite lacks NaF, which leads to the existence of Na(super +) vacancy in the lattice.
