| Popis: | Multiple quantum experiments are used to resolve broad peaks in nuclear magnetic resonance spectra of quadrupolar nuclei. In this work, we study phase cycling of radio frequency pulses in a single quantum satellite transition magic angle spinning experiment. The particular pulse sequence is a shifted echo sequence where phases of the pulses are varied in accordance with coherence selection rules. Experiments were performed on a $^{17}$O enriched sample of SiO$_2$. Results show that certain phase sequences may decrease the full width at half maximum of spectral peaks. Comment: 14 pages |
