a Data collected in \({{\bar{y}}^{{\prime} }}({zz})y^{\prime}\) scattering geometry; b data collected in \({{\bar{y}}^{{\prime} }}(x^{\prime} x^{\prime} )y^{\prime}\) scattering geometry. The dashed lines trace the new Raman scattering signals appearing at 700 K in \({{\bar{y}}^{{\prime} }}\left({x}^{{\prime} }{x}^{{\prime} }\right)y^{\prime}\) spectra. The mode assignment follows the arguments given in refs. 27,52. Spectra are vertically offset for clarity.
