	abstract = {Using a flow-tube reactor coupled to a chemical ionization mass spectrometer, we investigated the heterogeneous loss of OH on Halocarbon wax, two types of organized organic monolayers, and several solid organic surfaces (paraffin wax, stearic acid-palmitic acid mixture, pyrene, and soot) that are representative of surfaces found in the troposphere. The heterogeneous reaction is very efficient: the reaction probability is greater than 0.1 for all the organic surfaces investigated, except for Halocarbon wax. These results indicate that OH-organic heterogeneous reactions will significantly modify the hygroscopic properties and cloud condensation nuclei (CCN) ability of organic surfaces in the troposphere, and thus may play an important role in the Earth{\textquoteright}s radiative balance by affecting the properties of clouds. We also determined the diffusion coefficient of OH in helium to be 665 +/- 35 Torr cm(2) s(-1). This value is close to that of its polar analogue, H2O, suggesting that the diffusion coefficient of OH can be calculated accurately with H2O transport properties.},
