spectra (Table ). The DFT calculated quadrupolar parameters served as useful starting points to guide the fits (Table ). Static spectra were sensitive to the value of the CSA while MAS removed CSA broadening and resulted in spectra that were more sensitive to the isotropic shift and quadrupolar tensor. The positions of discontinuities in the powder lineshape from satellite transitions, where observed, were also used to determine the quadrupolar parameters. The calculated quadrupolar coupling constants matched the experimental values to within <5%.
