Figure 2
The Rietveld fit for sample A at 295 K (λ = 0.700667 Å, ID31 data). Open symbols, data; red line, final calculated pattern; lower black line, difference between the experimental data and the final refined model. The bars represent the Bragg reflections corresponding to the hexagonal structural model. The background intensity has been subtracted for clarity. The profile has been expanded by a factor of 10 at Bragg angles larger than 4°. Inset: magnification of the 4–6° 2θ regime. |
