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 27Al central transition to neighbouring 31P spins and to the central transition of a second 27Al. It confirms the correlation map characterizing the two 27Al and the 31P NMR signatures of 27Al–O–31P–O–27Al chemically bonded molecular motifs.
