HXeOBr in a xenon matrix

We report on a new noble-gas molecule HXeOBr prepared in a low-temperature xenon matrix from the HBr and N 2 O precursors by UV photolysis and thermal annealing. This molecule is assigned with the help of deuteration experiments and ab initio calculations including anharmonic methods. The H−Xe stret...

Description
Summary:We report on a new noble-gas molecule HXeOBr prepared in a low-temperature xenon matrix from the HBr and N 2 O precursors by UV photolysis and thermal annealing. This molecule is assigned with the help of deuteration experiments and ab initio calculations including anharmonic methods. The H−Xe stretching frequency of HXeOBr is observed at 1634 cm −1 , which is larger by 56 cm −1 than the frequency of HXeOH identified previously. The experiments show a higher thermal stability of HXeOBr molecules in a xenon matrix compared to HXeOH.
