Figure 15
Ambient-pressure Raman spectra of Pb₂SnO₄ powder and a single crystal in comparison to results from DFT-based calculations (a) and Experimental Raman spectra of a Pb₂SnO₄ single crystal at 16.0 (3) GPa in comparison to results from DFT-based calculations at 15.2 GPa carried out in space group Pnam (b). The frequencies of the calculated Raman spectrum were rescaled by 8%.
