摘要
Additional resonance lines emerged along the F-1 axis on a two-dimensional (2D) NMR spectrum, when the 2D spin-echo pulse sequence was applied to a solid-state homonuclear two-spin system with a negligibly small J-coupling constant under magic-angle sample spinning. We found that the positions of the lines are determined by the sample spinning frequency and the difference of the isotropic chemical shifts. (C) 1999 Elsevier Science B.V. All rights reserved.
