High-resolution heteronuclear correlation between quadrupolar nuclei.
Multiple-quantum magic angle spinning is successfully incorporated with double-quantum cross-polarization between quadrupolar nuclei, producing a two-dimensional 11B[27Al] high-resolution heteronuclear correlation spectrum for a magnesium aluminoborate glass. It is shown that the six-coordinate aluminum site (AlO6) preferentially coordinates to the tetrahedral boron site (BO4).
