Raman scattering of metastable phases of Si and Ge was performed in the pressure range 0 to 10 GPa. The results for Si are discussed in terms of the previously proposed BC8 and R8 structures. The first Raman spectrum of ST12‐Ge is also reported. We suggest that photochemically‐induced changes in ST1...
