摘要:

Composite pulse quadrupole echo sequences significantly reduce distortions due to finite pulse‐width effects, but they also produce phase dispersion leading to distortions of the quadrupolar powder line shape. In order to correct for phase errors arising from the composite pulse, we present the composite pulse magic echo sequence. It is demonstrated both experimentally and theoretically that the composite pulse magic echo sequence can eliminate phase distortions without considerably attenuating the signal‐to‐noise ratio. The performance of the new sequence is quite good.
