摘要：

High-pressure Raman spectroscopy of solid oxygen has been carried out at room temperature up to 110 GPa in order to study the recently observed structural transition at 96 GPa. The vibron and lattice phonons in the epsilon-O-2 phase corresponding to the transition became undetectable, although the vibron wave number in the epsilon-O-2 phase has shown a linear pressure dependence with a coefficient of 2.33 cm(-1)/GPa and reached 1753 cm(-1) at 94 GPa. Several bands have been recently observed above 25 GPa, and three of them we assigned to higher-order bands.
