摘要：

The response to spin-echo radiofrequency pulse excitation of a variety of nonintegral-spin quadrupolar nuclei (23Na, 27Al, and 93Nb) in inorganic solids (single-crystal ruby and sapphire, α-Al2O3, γ-Al2O3, AlN, NaNO3 KNbO3, NaNbO3, LiNbO3, albite, and the zeolite Linde A), subject to strong quadrupolar interactions and dipolar interactions of varying strength, is reported. It is demonstrated that "soft" RF pulse excitation with a pair of selective π/2 and π pulses yields predictable spin-echo decay behavior as a function of dipolar interaction, the experimental results being in good agreement with the theoretical predictions. © 1993 by Academic Press, Inc.
