    • b [22], which agrees with the experiment. At the highest pressures of observation of these vibrons (about 150 GPa), the ratio of intermolecular to intramolecular frequencies amounts approximately to 800/2450 ≈ 0.3, which corresponds to the ratio of 0.1 of the intermolecular to intramolecular force constant.

    • This is also consistent with recent electrical resistivity measurements of the nonmolecular phase at 193 GPa and 77 K [M.I. Eremets et al. (to be published)].
