Abstract

Multiple-quantum magic angle spinning (MQMAS) NMR spectrum of super27A1 via superH cross polarization (CP) was produced. The new technique was applied to the study of a fully hydrated A1POsub4-11 aluminophosphate. The combination of MQMAS and CPMQMAS gave new insights into the sample structure.

Abstract

A method combining multiple-quantum magic angle spinning (MQMAS) with S-observe, I-dephase rotational echo double resonance (REDOR), is presented. The MQ-REDOR technique was used in (super19)F-(super27)A1 spin pairs within a fluorinated aluminophosphate sample. It would be useful for spectral editing and in the study of internuclear distances in complex systems, that involve quadrupolar spins in conditions of high resolution.
