Abstract

Biogenic volatile organic compounds (BVOCs) are a class of molecules that have a noticeable effect on atmospheric chemical and physical processes. They are emitted naturally into the atmosphere mainly by plants and forests. An interesting family of this class is the monoterpenes (\chem{C_{10}H_{16}}) and terpenoids (oxygenated terpenes) which are unsaturated hydrocarbons that are formed by the combination of two isoprene units (\chem{C_5H_8}). These molecules are known to contribute to Secondary Organic Aerosol (SOA) and tropospheric ozone formation,\footnote{D. Kotzias, J. L. Hjorth, H. Skov, Toxicol Environ Chem 1989, 20–21, 95–99}$^,$\footnote{T. Hoffmann, J. R. Odum, F. Bowman, D. Collins, D. Klockow, R. C. Flagan, J. H. Seinfeld, J. Atmos. Chem. 1997, 26, 189–222} mainly through oxidation pathways. In addition, these molecules can form Hydrogen-bonded complexes with surrounding atmospheric molecules. The synergic combination of quantum chemical calculations and Fourier transform microwave spectroscopy (FTMW) in jet-cooled conditions, is a powerful tool to study the gas phase micro-solvation of atmospheric relevant molecules. Many hydrated complexes were studied using this approach in our group.\footnote{E. M. Neeman, J. R. Avilés Moreno and T. R. Huet, Phys. Chem. Chem. Phys. 2021,23, 18137-18144}$^,$\footnote{E. M. Neeman, N. Osseiran and T. R. Huet, J. Chem. Phys. 2022, doi.org/10.1063/5.0084562} We present herein a new approach, which employs the same theoretical-experimental approach to characterize complexes of terpenoids, i.e., alcohols and ketones, with \chem{H_2S}, an atmospheric trace gas. The observed complexes are compared to their analog hydrates. The present work was funded by the ANR Labex CaPPA, by the Regional Council Hauts-de-France, by the European Funds for Regional Economic Development, and by the CPER CLIMIBIO.
