Oxidation by ozone of linoleic acid monolayers at the air-water interface in multi-component films at 21 °C and 3 °C.

Aqueous aerosols are often covered in thin films of surface-active species, such as fatty acids which are prominent components of both sea spray and cooking emissions. The focus of our study is one-molecule thin layers of linoleic acid (LOA) and their behaviours when exposed to ozone in multi-component films at the air-water interface. LOA's two double bonds allow for ozone-initiated autoxidation, a radical self-oxidation process, as well as traditional ozonolysis.
