(a) FT magnitudes of the k3-weighted extended X-ray absorption fine structures measured above the Br K-edge for a PbBr2 solution in diethylene glycol at 357 K in the upstream (dashed line) and the downstream process after heating to 433 K and cooling to 357 K (solid line). (b) Comparison of k3-weighted FT magnitudes of the extended X-ray absorption fine structures measured above the Br K-edge for several PbBr2 reference compounds as indicated. A: solution at 357 K in the upstream process. B: solid crystalline PbBr2 · C4H10O3. C: crystalline PbBr2. Data are shifted vertically by 0.4 and are not corrected for phase shifts. FT in the range 2 Å−1< k < 11.6 Å−1. |
