文摘
We report an open-shell species containing xenon, HXeO (2
), prepared by UV photolysis of H2O/Xe or N2O/HBr/Xe solid mixtures at 7 K and subsequent thermal mobilization of oxygen atoms at 
30 K. The H-Xe stretching absorption of HXeO in solid Xe is at 1466.1 cm-1, and it shifts to 1070.3 cm-1 upon deuteration. The extensive ab initio calculations indicate that HXeO is intrinsically stable, owing to significant ionic and covalent contributions to its bonding. The formation of HXeO (2) radicals in these experiments suggests extensive stabilization and thermal mobility of singlet (1D) oxygen atoms in solid Xe and holds promises for the stability of the HKrO and HArO species.
