Many of the combined cross polarization-magic angle spinning (CP-MAS) experiments that have been developed over the past ten years for structural studies of chemical and biological systems rely on the measurement of quantitative signal intensities. However, one of the drawbacks of the CP technique i
spectra of aluminium acetylacetonate show distinct lineshapes depending on the experimental conditions as the different orientations within the powder cross-polarize with differmg efficiencies. Selective polarization transfer to the l/2++-l/2 transition occurs at rfpower levels corresponding to 3w,
