The 2-dimensional solid-state nutation NMR expt. for the detn. of quadrupole parameters, as introduced by Samoson and Lippmaas (1983) is evaluated. A complete series of spectra (for spin I = 3/2, 5/2, 7/2, and 9/2) resulting from d.-matrix calcns. is presented, and some exptl. aspects of the method are discussed. Applications of the method to 27Al (I = 5/2) in spodumene and to 45Sc (I = 7/2) in Sc2(SO4)3 are shown.
