Abstract
- Under MAS conditions at 60 kHz, 1H-27Al cross-polarization is efficient process.
- We found that very weak 27Al RF pulses can be applied.
- We tested Hartmann-Hahn (H-H) match with 27Al RF pulses equal to 3.3 kHz and 8.3 kHz.
- Double quantum (DQ) CP for the 3.3 kHz 27Al RF pulse is the best choice for H-H set.
- Method is useful for mapping of the distribution of OH groups on the alumina surface.
