High-resolution 1H NMR in the solid state using symmetry-based pulse sequences
High-resolution 1H NMR in the solid state using symmetry-based pulse sequences
We demonstrate new rotor synchronised pulse sequences for obtaining high-resolution H-1 NMR spectra in the presence of fast magic angle spinning (MAS). The new sequences exploit selection rules generated by appropriate synchronisation of the radio-frequency (rf) field modulations and the sample rotation. We show preliminary results demonstrating the feasibility of high-resolution proton NMR spectroscopy in the presence of fast MAS, and also demonstrate the resolution of H-1-C-13 J-couplings in the solid state.

Abstract
We demonstrate new rotor synchronised pulse sequences for obtaining high-resolution H-1 NMR spectra in the presence of fast magic angle spinning (MAS). The new sequences exploit selection rules generated by appropriate synchronisation of the radio-frequency (rf) field modulations and the sample rotation. We show preliminary results demonstrating the feasibility of high-resolution proton NMR spectroscopy in the presence of fast MAS, and also demonstrate the resolution of H-1-C-13 J-couplings in the solid state.
