Aluminum to oxygen cross-polarization in alpha-Al2O3 (corundum).
Experimental results concerning the cross-polarization of two quadrupolar, I = 5/2 nuclei are presented. It is shown in particular that 27Al spins in alpha-Al2O3 (corundum) can be spin-locked, and magnetization transferred to the 17O spin system. Cross-polarization between pairs of quadrupolar nuclei can cause considerable signal-to-noise ratio gains over conventional one- (or two-) pulse excitation and should be of use in investigating a number of inorganic solids.
