Circulaire 3, B-1180 Brussels, Belgium Department of Chemistry, KULeuven, Celestijnenlaan 200F, B-3001 Heverlee, Belgium Introduction A major area of uncertainty in tropospheric chemistry is the role of the biogenic volatile organic compounds. In particular, the role of the terpenes is largely unknown, although their global emissions are believed to outweigh the anthropogenic emissions of non-methane hydrocarbons. While it is well established that the terpenes react initially with hydroxyl radicals, ozone and nitrate radicals, their further reaction paths still need to be elucidated in laboratory experiments. Here a fast-flow reactor technique with
