The Raman spectrum of brookite, TiO2 (Pbca, Z = 8)
Abstract
The Raman microprobe spectra of natural brookite crystals from Switzerland and Brazil and a synthetic brookite powder exhibit a characteristic intense band at 153 cm−1. In contrast, anatase has a band of similar intensity at 144 cm−1 and rutile lacks a strong band in this region. Polarization experiments with the Brazilian crystal permit 17 out of a predicted 36 vibrational bands to be readily assigned as A1 g (127, 154, 194, 247, 412, 640 cm−1), B1 g (133, 159, 215, 320, 415, 502 cm−1), B2 g (366, 395, 463, 584 cm−1) and B3 g (452 cm−1). Eight weaker bands and component sub‐bands resolved at 172, 287, 545, 618 cm−1, 254, 329, 476 cm−1 and 497 cm−1 are tentatively assigned to B3 g, B2 g and A1 g modes respectively. Traces of Si and Fe in the Brazilian crystal and Si, Fe, Al and S in the Swiss sample are indicated by spot electron microprobe analysis. Electron spin resonance spectra suggest small amounts of Fe 3+ are substituting for Ti 4+ in the structure. Concomitant protonation of oxygens to maintain charge balance yields OH groups which give rise to three sharp, low‐intensity absorption bands near 3360, 3380 and 3404 cm−1 in the infrared spectra. X‐ray photoelectron spectroscopy shows that surface‐bound OH/H 2 O species exist in both crystals but no detectable Ti 3+.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
