摘要：

Raman spectra of fluid and solid oxygen have been measured at temperatures near 298 K to pressure greater than 180 kbar (18 GPa). At 298 K, fluid oxygen freezes at 59.1±0.5 kbar which is 2 kbar higher than the freezing pressure of n-H2 at this temperature. Solid-solid phase transitions are observed near 96 and 99 kbar. The phase boundaries near room temperature and the intense visible absorption spectra of the very high pressure phase are described. © 1979.
