We describe a new solid-state NMR imaging technique for abundant spins using magic sandwich echoes (MSE). Simple modification of the original MSE pulse sequence enables highly elXcient narrowing of broad NMR lines in solids, allowing high resolution imaging. Wider signal observation windows than tho

A multi-dimensional NQR technique to image both the spatial distribution of quadrupolar nuclei and the local orientation of the electric field gradient tensor at the quadrupole sites in solids is reported. The encoding procedure is based on the irradiation of the sample by a pulse sequence composed
The present communication demonstrates, for the ยฎrst time, that 31 P/ 27 Al double resonance solid-state NMR experiments such as cross-polarization (CP) can be used to map out the connectivity in the intermediate gel phases of molecular sieve synthesis. Our work clearly highlights the advantages of
