N2 - Experimental and theoretical results concerning the quantitative determination of non-integral-spin quadrupolar nuclei in static solids using spin-echo nuclear magnetic resonance are presented for the cases of selective, nonselective. and "partially" selective excitation. For a strong quadrupolar coupling, selective excitation of the central (1 2, - 1 2) transition is shown to give excellent quantitative results on systems of known composition, using both in-phase and 90°-phase-shifted pulse sequences. Off-resonance effects are manifested as intensity oscillations, from which nuclear quadrupole coupling constants may be estimated.
