The importance of peroxy radical reactions in the upper troposphere and lower stratosphere (UTLS) region are well known. The reaction between peroxy radicals and NOx species is a notable example, influencing as it does ozone (O3) concentrations within this region. Previous kinetic studies have been performed over small ranges of temperature and pressure and have thus been very limited. The result of these studies is a wealth of data that needs extrapolation to UTLS region parameters before it can be compared accurately with atmospheric conditions. The main target of this work was the development of a unique analytical tool for the study of peroxy radical reactions, a chemical ionisation mass spectrometer (CIMS) turbulent flow system, capable of the detection and identification of both the reactant and product species. The system was designed and became operational. Experimental work has focused on laboratory studies of reaction kinetics, data reported in this work representing the reactions of hydroperoxy and methylperoxy radical reactions with NO2 and the reaction between HO2 and NO over wide temperature and pressure ranges (190 — 298 K and 70 — 760 Torr).
