Short summary
The sources of radicals at aerosol surfaces are highly uncertain. Here we investigate the HO2 radical production from the UV irradiation of imidazole-2-carboxaldehyde (IC) in bulk aqueous films containing IC and citric acid, as well as IC in ammonium sulfate aerosols. We find that IC is an efficient photosensitizer that forms HO2 radicals from H-donor chemistry. IC is a proxy species for brown carbon in atmospheric aerosols.
The sources of radicals at aerosol surfaces are highly uncertain. Here we investigate the HO2...
