Title: X-ray induced mobility of molecular oxygen at extreme conditions

Abstract

An in situ Raman study of KClO4 irradiated with x-rays in a diamond anvil cell is reported. Decompn. via KClO4 + hν → KCl + 2O2 was monitored via the O2 vibron at 2, 6, and 9 GPa. For all pressures, the vibron grew in intensity and then diminished after successive irradn. suggesting that O2 was diffusing away from the irradiated region. The diffusion rate accelerated with pressure increase, indicating that the nonhydrostatic pressure gradient was likely driving mol. diffusion of O. At 9 GPa, the vibron bifurcated suggesting that O2 exists as 2 forms: interstitial and bulk solid. As a result, this method can be used to study molecular diffusion under extreme conditions.
