摘要: 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 exploit selection rules generated by appropriate synchronisation radio-frequency (rf) field modulations and sample rotation. show preliminary results demonstrating feasibility proton spectroscopy MAS, also resolution H-1-C-13 J-couplings solid state.
