High-pressure synchrotron x-ray diffraction and Raman spectroscopic study of plumbogummite |
(color online) Fitted plumbogummite Raman profiles obtained at pressures of (a) 0 GPa and (b) 2.6 GPa (thin blue lines: experimental Raman spectra; green lines: fitted peaks; red lines: entire fitted Raman profiles obtained by the superposition of the fitted peaks). |
