Pl. Bryant et al., Al-27 field-swept and frequency-stepped NMR for sites with large quadrupole coupling constants, SOL ST NUCL, 16(1-2), 2000, pp. 63-67
Spectra of nonspinning samples with large quadrupole coupling constants, 16
-32 MHz, are acquired by frequency-stepping. A series of spin-echoes are ac
quired at arbitrary frequency increments, frequency-shifted in the time dom
ain, and co-added as magnitude spectra. This procedure is derived from a me
thod in use for field-swept NMR. The two methods are compared. (C) 2000 Els
