摘要：

We achieve a significant signal enhancement for the triple-quantum magic-angle spinning NMR of aspin-3/2 system, by using an amplitude-modulated radiofrequency field, followed by a selective 90degrees pulse and a phase-shifted strong rf field, for the triple-quantum excitation, and an amplitude-modulated radiofrequency field for the conversion of triple-quantum coherence to observable single-quantum coherence. The experiment is demonstrated on the Rb-87 NAIR of polycrystalline rubidium nitrate. (C) 2002 Elsevier Science (USA).
