摘要：
Experimental proof is given for the enhancement of spectral resolution of the H-1 MAS NMR spectra of aluminium-rich zeolites by the increase of the resonance frequency (up to 500 MHz) and the spinning rate (up to 11 kHz). Quantum-mechanical calculations are presented which allow a quantitative discussion of the influence of the resonance frequency and the spinning rate on the residual linewidth of the MAS NMR signals of spin-1/2 nuclei.
