Short summary

OH and HO₂ radicals are important trace constituents of the atmosphere that are closely coupled via several types of reaction. This paper describes a new laboratory method to simultaneously determine OH kinetics and HO₂ yields from chemical processes. The instrument also provides some time resolution on HO₂ detection allowing one to separate HO₂ produced from the target reaction from HO₂ arising from secondary chemistry. Examples of applications are presented.
