Having established that the three materials exhibit the same type of electronic structure we continued by elucidating this electronic state. We began by examining the shift tensor parameters, which display considerable differences among the different samples (see Table ), which is unsurprising since variation of the isotropic shift with sample composition was already detected in the MAS spectra (see Fig. and Table ). We note that there are significant discrepancies between isotropic shift values determined under MAS and static conditions, which arise due to an inherent imprecision of fitting the broad static lineshapes. Therefore, we used only the isotropic shift values (see Table ) estimated from MAS spectra to draw conclusions about properties of the oxyhydrides.
