Matrix reaction of ozone with Cl2 and Br2. FTIR identification of BrC10 and ClBrO species

Photolysis of argon samples containing Cl 2 , Br 2 , O 3 with 800-360 nm irradiation produced new absorptions at 940.9-932.7 and 818.9-817.5 cm −1 , which were assigned to the new BrClO and ClBrO species. Formation of these species proceeds through photodissociation of BrCl: O 3 and ClBr: O 3 complexes. Photolysis of ClBrO molecules above 400 nm produced BrCl species.
