Through-bond homonuclear correlation experiments in Solid-state NMR applied to quadrupolar nuclei in Al-O-P-O-Al chains.
Résumé
Through-bond homonuclear correlation experiments can be realised in solids between spins of type X, separated by four chemical bonds, in X-O-Y-O-X motives, provided a J coupling 10 between X and Y exists: central transitions of quadrupolar 27Al spins can be correlated via the J2 scalar coupling between 27Al (X) and 31P (Y) in materials featuring Al-O-P-O-Al motives.
