The Rare Gas Photosensitized Exchange Reaction between Hydrogen and Deuterium

Abstract

AbstractThe krypton and xenon photosensitized exchange reaction between hydrogen and deuterium occurs with a quantum yield close to unity. Initial rate studies as a function of total hydrogen pressure indicate that homogeneous as well as heterogeneous reactions contribute to product formation. A mechanism with a strong interaction between excited sensitizer atom and substrate molecule is suggested to be responsible for the transfer of energy in this system.
