High resolution ~9F NMR spectra of rotating polycrystalline solids can be obtained by single pulse excitation with a long delay before acquisition (SPEDA). However, the overall spectral range is influenced by the chemical shift anisotropy which, unlike the situation for protons, might be large for 1
