(a)–(f). Fits of the calculated to the experimental powder diffraction pattern after Rietveld refinement for (a) β-P.O. 36, (b) P.O. 62, (c) P.Y. 151, (d) α-P.Y. 154, (e) β-P.Y. 181 and (f) P.Y. 194. The experimental data points are shown as points, the calculated patterns as lines and the difference curves as lines under the profiles. Reflection positions are shown as vertical dashes. |
