Abstract
The recent report(1) that the Fe K-edge X-ray absorption fine structur e (XAFS) recorded from FeTiO3 are best interpreted in terms of the pre sence of Fe3+ is erroneous. The X-ray absorption near edge structure r ecorded at both the Fe K- and Ti K-edges are consistent with the prese nce of Fe2+ and Ti4+. The results are endorsed by Fe-57 Mossbauer spec troscopy. The compound FeTiO3 is accurately formulated as Fe2+Ti4+O3.
