Étude, en atmosphère simulée, de la réactivité de trois composés biotiques d'impact atmosphérique majeur :
l'isoprène, le MBO et le sabinène.

Abstract : Some volatile organic compounds (VOC) are emitted in the atmosphere due to the natural activity of vegetation and oceans. These biotic species can react with different aggressors in the atmosphere,
especially OH radicals and ozone during the day. This work focuses on the study of the chemical reactivity of three biotic compounds : Isoprene, MBO and sabinene. These three species have been
chosen because of their abundant emissions and the lack of the knowledge of their chemical reactivity.
To obtain a complete vision of their degradation in the atmosphere, several aspects of their reactivity have been considered:
First the kinetics and the mechanisms of their reactions with OH radicals and with ozone,
Then the study of the degradation processes of their own primary products in the atmosphere.
Thus this work contributes to a better understanding of the atmospheric impacts of the reactivity of
these three particularly important BVOC.
