Internuclear couplings between selected homonuclear spin pairs in a multiply-labelled spin system are determined by NMR spin echo experiments in the solid-state. The spin echoes are induced by an amplitude-modulated shaped pulse. The time shift in the echo modulation curve is treated by average Hamiltonian theory and verified by numerical simulation. The J-couplings may be estimated by experiments on samples spinning at the magic-angle, while the direct dipole-dipole couplings may be estimated by off-magic-angle spinning. The concept is tested on a uniformly C-13-enriched sample of L-histidine hydrochloride monohydrate. (C) 2008 Elsevier B.V. All rights reserved.
