A new molecular solid phase of carbon dioxide at high pressure and temperature

PDF Version Also Available for Download.

Description

We report the discovery of a new high-pressure molecular phase of carbon dioxide. The new polymorph, CO{sub 2} -IV, is formed by heating the high-pressure orthorhombic phase III to temperatures above 1000K at pressures between 12 and 33GPa. Analysis of the Raman spectrum of the new phase suggests a structure lacking inversion symmetry.
