| Abstract: | 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. |
