摘要
A novel solid-state NMR method for the combined rotation and multiple-pulse spectroscopy (CRAMPS) of homonuclear dipolar-coupled nuclei is introduced. Using a magic-sandwich sequence with z-rotational decoupling, high-order truncation of the dipolar interaction is combined with improved performance under resonance offsets and spinning speeds higher than those typically used in conventional CRAMPS. The method is described using average Hamiltonian theory to third order and demonstrated experimentally by H-1 CRAMPS of rigid organic solids. (C) 1997 Elsevier Science B.V.
