References for composite-pulse nutation NMR

When we apply the one-pulse sequence to nuclei with low gyromagnetic ratio, spurious signals that distort the base line of the NMR spectrum are observed. The composite-pulse sequence, introduced by M. Mehring's group, cancels these spurious signals. There are three consecutive RF pulses in this sequence.

References containing data and graphs that can be simulated with the composite-pulse applets, in order to determine the quadrupole coupling from a featureless NMR lineshape, are provided:
