Short summary
Oxidation of bromide and iodide is an important process in the troposphere that leads to gas-phase halogen compounds which impact the oxidation capacity of the atmosphere. Imidazole-2-carboxaldehyde (IC), an aromatic carbonyl, is a product of the multiphase chemistry of glyoxal (an oxidation product of isoprene), a major biogenic volatile organic compound. In this study we demonstrate that IC photochemistry leads to efficient oxidation of bromide and iodide and liberation of halogen compounds.
