HXeOBr in a xenon matrix

subject

description

We report on a new noble-gas molecule HXeOBr prepared in a low-temperature xenon matrix from the HBr and N2O 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. peerReviewed
