## Abstract Composite pulses that compensate for resonance offset and electric field gradient inhomogeneity are proposed for broadband excitation of pure nuclear quadrupole resonance systems in powders. The excitation band width of the composite pulse sequences was obtained with a numerical calcula
It is shown here that NQR pulses can be treated in a consistent way leading to expressions based upon SU( 2) algebra. The use of various bases (fictitious spin l/2, spherical tensors) is not necessary. One consequence is that shaped pulses designed for NMR can be used for NQR.
