High-pressure phases of a hydrogen-rich compound: Tetramethylgermane
High-pressure phases of a hydrogen-rich compound: Tetramethylgermane
The vibrational and structural properties of a hydrogen-rich Group IVa hydride, Ge(CH$_3$)$_4$, are studied by combining Raman spectroscopy and synchrotron X-ray diffraction measurements at room temperature and at pressures up to 30.2 GPa. Both techniques allow the obtaining of complementary information on the high-pressure behaviors and yield consistent phase transitions …
