Abstract: While the composite pulise solid echo sequences reduce the effects of finite pulse width greatly, they do not eliminate them completely, and they introduce a new type of distortion into the powder lineshape, that is, the phase error. The present paper analyzed the composite pulse, and used it to construct the Magic Echo Sequence for I=1 spin systems for compensating the phase error. The theory was confirmed by computer simulations and experimental results. It is clear that the performance of the composite pulse Magic Echo Sequence is superior to that of the composite pulse solid echo sequences, and essentially solved the problems due to finite pulse width effects for ²D-NMR spectroscopy.
