Raman spectroscopy of three isotopes of hydrogen under very high compression yields evidence of a new phase of hydrogen—phase V—which could potentially be a precursor to the long-sought non-molecular phase. A non-molecular phase of hydrogen? Under extremely high pressures, hydrogen molecules are pre...
