Abstract

The present state of knowledge of organic, or carbon-based, peroxy radicals (RO(2)) is reviewed. Data on the chemical and physical properties of peroxy radicals in the gas phase are considered, as well as the role of peroxy radicals in tropospheric chemistry and measurements of their concentrations in the atmosphere. Where appropriate, peroxy radicals are grouped together by type (alkyl, acyl, oxygen-substituted, halogen-substituted and aromatic radicals) to facilitate comparison. Data on the hydroperoxy radical (HO(2)) are included where they are directly relevant to measurements on organic peroxy radicals, for example absorption cross-sections used in measurements of RO(2) + HO(2) rate constants. The literature data are reviewed critically and recommendations for absorption cross-sections, rate constants and branching ratios are made where appropriate.
