Matrix-isolation infrared spectra of HOOBr and HOBrO produced upon VUV light irradiation of HBr/O2/Ne system

►HOOBr and HOBrO are generated by the VUV photolysis of HBr/O2 isolated in a Ne matrix. ►IR bands of HOOBr and HOBrO are assigned by isotope-labeled experiments and CCSD calculation. ►Both isomers of HOOBr and HOBrO are found to decompose upon UV irradiation.
