17O multiple-quantum and 1H MAS NMR studies of zeolite ZSM-5

Oxygen-17 multiple-quantum magic-angle spinning nuclear magnetic resonance studies were performed, for the first time, in the high field of 17.6 T. A good resolution between two oxygen signals due to SiOSi and SiOAl fragments could be obtained. From the residual linewidth of the SiOSi signal, it is...

Description
Summary:Oxygen-17 multiple-quantum magic-angle spinning nuclear magnetic resonance studies were performed, for the first time, in the high field of 17.6 T. A good resolution between two oxygen signals due to SiOSi and SiOAl fragments could be obtained. From the residual linewidth of the SiOSi signal, it is concluded that a change of the bridging SiOSi angle by 13.4° gives rise to a quite large change in the isotropic chemical shift of less than 5.7 ppm.
