The far-infrared spectrum of phases III and IV of solid CH4 have been investigated. Five bands were observed in phase III. Discontinuous changes in the linewidths and the emergence of a new band arc associated with the transition to phase IV. On the basis of the measured Griineisen parameters, the b

The volume and temperature dependences of the infrared absorption spectrum of phase II of CH, have been studied. One of the infraredactive translational modes was found to soften on approaching the transition to phase I. Mode of Griineisen parameters and the isothermal compressibility were obtained
## Abstract The phase behavior of the methaneβcarbon dioxide system has been determined experimentally along the solidβliquidβvapor locus. Pressureβtemperature measurements were made along this locus from the triple point of carbon dioxide to β284Β°F. Compositions of the vapor phase along the solidβ
