    • Despite these corrections, it is still possible to observe vestiges of disruptions present in the compounds' raw data and also already pointed out in the KBr spectra (Figure S1). Their persistence may be due to the fact that the corrections cannot account for the variation with the samples of the sensitivity of the measurement setup (this one being tuned automatically).

    • In the case of the transitions we have observed, we also discard the possibility of d-d transitions for similar reasons. Mössbauer studies of the HiPIP models performed at 77 K indicate no valence trapping (results will be published elsewhere).
