Short summary

Few studies have compared the molecular and optical evolution of smoke extracts during aqueous photooxidation. Here, OH-initiated aqueous photodegradation of two smoke extracts was investigated. Optical and molecular changes were characterized using a combination of analytical techniques. Reactive oxygen species contributions and potential reaction mechanisms were also examined. These results improve understanding of aqueous photochemistry and support more accurate representation in atmospheric models.
