Through-bond correlation experiments can be realised in solids between spins of type X, separated by four chemical bonds, in X-O-Y-O-X molecular motives, provided a scalar coupling (J) between X and Y exists. In the 2D-Homonuclear-Heteronuclear Single Quantum Correlation (H-HSQC) experiment presented here, the central transitions of quadrupolar 27Al spins can be correlated via the scalar coupling J2 between 27Al (X) and 31P (Y) in materials featuring Al-O-P-O-Al motives. A 3D homonuclear/heteronuclear correlation experiment can also be performed, providing the correlation map characterizing the two 27Al and the 31P NMR signatures of 27Al-O-31P-O-27Al chemically bonded molecular motifs.
