中文摘要 | Solid methane has been studied by Raman scattering under high pressure in a diamond anvil cell at room temperature. Internal modes nu(1) and nu(3) have been followed up to 208 GPa. The results indicated that methane remained in molecular form and kept its high- pressure phase structure to the highest pressure investigated. Fitting x- ray diffraction data from the literature by the Vinet equation of state from 16.9 to 37 GPa gives values of K-0 = 6.4 +/- 0.73 GPa, K-0(') = 5.68 +/- 0.36 and V-0 = 25.44 cm(3) mol(-1). Extrapolation of the above equation of state showed that the volume of methane changes from 11.84 to 6.63 cm(3) mol(-1) as pressure increases from 34 to 208 GPa. Furthermore, the metallization pressure of solid CH4 has been roughly estimated on the basis of our recent results and extrapolated equation of state. |
