Abstract
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 evier Science B.V. All rights reserved.
