Figure 4
(a) Details of the 131/311/113 reflections (2.28 < d < 2.36 Å) at temperatures ranging from 4.2 to 1073 K, (b)–(d) curve-fitting results of the same region at 100, 673 and 773 K, respectively. Note the abscissae in (b)–(d) are time-of-flight, related to d-spacing by t (ms) = 48.235d (Å). The solid line through the data points in (b)–(d) is the envelope of the Voigt/sharp-edged exponential peak fits and the vertical lines indicate the individual peak intensities and positions (with error bars). |
