We report Raman scattering and visible to near-infrared absorption spectra
of solid hydrogen under static pressure up to 285 GPa between 20 and 140 K.
We obtain pressure dependences of vibron and phonon modes consistent with
results previously determined to lower pressures. The results indicate the
stability of the ordered molecular phase III to the highest pressure reache
d and provide constraints on the insulator-to-metal transition pressure.
