抄録

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 phase transition at 96 GPa. The vibron and lattice phonons of ε-phase corresponding to the transition became undetectable although the vibron wavenumber in ε-phase has shown a line pressure dependence with a coefficient of 2. 33 cm<SUP>-1</SUP>/GPa and reached 1753cm<SUP>-1</SUP> at 94 GPa. This result provided evidence that the structural transition is accompanied by a insulator-metal transition. The results have been discussed with a view to molecular dissociation comparing with those of the other Vlb elemental materials.
