1. Relaxation-assisted separation of chemical sites in NMR spectroscopy of static solids

Author

Lupulescu, Adonis, Kotecha, Mrignayani, Frydman, Lucio, and Bowers, Michael T.

Subjects
Chemistry, Physical and theoretical -- Research, Nuclear magnetic resonance spectroscopy -- Usage, Chemistry
Abstract

The potential use of relaxation times toward the resolution of inequivalent chemical sites in the NMR spectroscopy of powdered or disordered samples is discussed. The proposal is motivated by the significant differences that could often be detected in the relaxation behavior of sites in solids.

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

Author

Abstract

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.
