摘要

We present here the first 3D homonuclear/heteronuclear correlation experiment applied to quadrupolar nuclei and making use of the sole scalar J-coupling. This experiment, based on the 2D-Homonuclear-Heteronuclear Single Quantum Correlation (H-HSQC) experiment, uses a relayed transfer from the Al-27 central transition to neighbouring P-31 spins and to the central transition of a second Al-27. It confirms the correlation map characterizing the two Al-27 and the P-31 NMR signatures of Al-27-O-P-31-O-Al-27 chemically bonded molecular motifs. (c) 2006 Elsevier Inc. All rights reserved.
