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 calculation procedure and confirmed by 35 Cl experimental spectra of powdered NaClO 3 .
