  • Drastic transformation of tetrahedral molecules at high pressure
    Shinji Tsuneyuki, Jun Tsuchiya, Review of High Pressure Science and Technology/Koatsuryoku No Kagaku To Gijutsu, 13,   2003 09 , Recent applications of the first-principles molecular dynamics method to the study of the structural transformation of some tetrahedral molecules are reported. Contrary to the interpretation of shock-wave experiments, CH 4 was found to dissociate into a mixture of hydrocarbons below 100 GPa and separate into diamond and hydrogen only above 300 GPa. The fcc-phase of SnI4 above 60 GPa was unambiguously shown to be a substitutional solid solution of Sn into fcc I. B2H6, in which BH 4 tetrahedra shares an edge, will undergo more extensive polymerization leaving fewer isolated hydrogen molecules.
