Composite pulses designed to compensate the inhomogeneity of the radio-frequency field using numerical calculation procedures in spin-l NQR in powders are presented. It is demonstrated by computer simulation and experimental result that the perforrnanceofthe proposed composite pulses, ( ),( 1gO)90 a
Goldman's spin-1/2 formalism has been used for describing the response of an I=3/2 spin system to a two-pulse sequence in a pure nuclear quadrupole resonance experiment. A detailed analysis of the polarization evolution and quadrupolar echo generation is carried out through the use of explicit expre
