In the atmosphere, the degradation of organic pollutants such as Volatile Organic Compounds (VOCs) is induced by the most important atmospheric oxidant: the hydroxyl radical OH. This degradation leads to the formation of peroxy radicals: hydroperoxy HO2 and alkylperoxy RO2. These radicals play a major role in tropospheric chemistry. The reactivity of RO2 and HOX (HO2 and OH) radicals controls the oxidative capacity of the atmosphere and the formation of tropospheric ozone and secondary pollutants. In remote environments (or “clean environment” such as tropical forests or marine boundary layer), where the concentration of nitrogen oxides (NOx) is low, the reactions between RO2 and HOx dominate the atmospheric chemistry. However, this chemistry is still poorly known and controversial in the literature. The uncertainties and/or lack of data on RO2+HOx reactions rates and branching ratios can lead to important errors on modelling of ozone and radical concentrations in the atmosphere. The aim of the present work is the development of a new and innovative experimental device to bring new experimental results for the reactions RO2 + HOx. The new setup consists of a fast flow tube coupled to three complementary techniques: Laser Induced Fluorescence (LIF) for OH radical measurements, continuous wave Cavity Ring-Down Spectroscopy (cw-CRDS) for HO2 radical measurements and Mass Spectrometry with Molecular Beam sampling (MB/MS) for measurement of stable reaction products and radical species. First, each of the three techniques has been validated independently, and then the validation of the complete system was done through the study of different known reactions between a stable species (ethane, propane, methanol, CO) and OH radicals. Two methods of OH radicals generation in the reactor were used: through the reaction F+H2OOH+HF and the reaction H+NO2OH+NO. An unexplained OH recycling phenomenon in the reactor has been observed for all reaction partners (except CO) when using F+H2O as precursors. This was confirmed during the study of reactions involving the same deuterated species. In this manuscript, the different tests that have been carried out in order to understand this phenomenon are described

HOx (OH+HO2) and RO2 radicals are involved in oxidation processes in the gas phase, generating secondary products impacting the air quality and human health. Understanding these oxidation processes through the quantification of these radicals is still challenging because of their low concentrations (

The hydroxyl radical OH and hydroperoxy radical HO2 radicals are key species in many oxidation processes in the atmosphere. The degradation of volatile organic compounds under tropospheric conditions is induced by reactions with hydroxyl radicals followed by the subsequent chemistry of the initial OH oxidation products with O2. This thesis was focused on the kinetic study of some of these atmospherically relevant reactions to better understand their oxidation mechanisms using an experimental system of laser photolysis coupled to Laser Induced Fluorescence (LIF, for OH radical) and continuous-wave Cavity Ring-Down Spectroscopy (cw-CRDS, for OH, HO2 and RO2 radicals) detection techniques. After determining the infrared spectrum of OH, HO2 and CH3O2 radicals in the near infrared region and the absorption cross-sections of few selected lines, four systems were studied with the above mentioned techniques: CH3O2 + OH, C2H5O2 + OH, C3H7O2 + OH and C4H9O2 + OH. The rate constant and the HO2 yield of the four reactions were determined. In addition, the rate constants of few secondary reactions such as CH3O + HO2, CH3O + CH3O or OH + HO2 have been determined
