Popis: Vacuum ultraviolet (VUV) light photolysis of an HBr/O 2 mixture in a Ne matrix has produced HO 2 Br isomers (HOOBr and HOBrO), which are important reaction intermediates in atmospheric chemistry. The observed bands have been assigned with an aid of a quantum chemical calculation at CCSD/aug-cc-pVDZ. These assignments have been confirmed by the experimental results using isotopic species of 18 O 2 or DBr. Their characteristic bands are discussed in comparison with those of HOOCl and HOClO from an HCl/O 2 mixture [7] . Both HOOBr and HOBrO are found to be photolyzed with the UV light below 385 nm.
