Abstract
In this article, optical absorbtion and band structure of solid molecular hydrogen at five different phases are reported. Transition pressure for the non-metallic phase to the metallic phase is found at 284 GPA. Phase-IV and phase-V of solid molecular hydrogen are observed as metallic. It is also observed that UV-visible spectra of molecular hydrogen is also changing significantly with the change of pressure.
