Figure 2
X-ray powder diffraction patterns acquired at 298 K from (a) Gly(d5)·MgSO4·5D2O and (b) Gly(d5)·MgSO4·3D2O. Red symbols represent the measured data, green lines the result of Rietveld refinement, pink lines the difference profile and black tick marks the expected positions of each Bragg reflection. Note the use of square-root Iobs on the vertical axis to emphasize the weaker peaks. The insets show the strongest peaks from different accessory polymorphs of glycine in each specimen. |
