Aqueous solutions as well as mixed (NH4)2SO4-levoglucosan particles were exposed to OH. In both cases, samples experiencing different extents of processing were isotopically analyzed by Thermal Desorption-Gas Chromatography-Isotope Ratio Mass Spectrometry (TD-GC-IRMS). From the dependence of levoglucosan δ13C and concentration on the reaction extent, the kinetic isotope effect (KIE) of the OH oxidation reactions was determined to be 1.00187±0.00027 and 1.00229±0.00018, respectively. Both show good agreement within the uncertainty range. For the heterogeneous oxidation of particulate levoglucosan by gas-phase OH, a reaction rate constant of (2.67±0.03)·10−12 cm3 molecule−1S−1 was derived. The laboratory kinetic data, together with isotopic source and ambient observations, give information on the extent of aerosol chemical processing in the atmosphere.}, cin = {IEK-8 / IBG-2}, ddc = {550}, cid = {I:(DE-Juel1)IEK-8-20101013 / I:(DE-Juel1)IBG-2-20101118}, pnm = {243 - Tropospheric trace substances and their transformation processes (POF3-243) / HITEC - Helmholtz Interdisciplinary Doctoral Training in Energy and Climate Research (HITEC) (HITEC-20170406)}, pid = {G:(DE-HGF)POF3-243 / G:(DE-Juel1)HITEC-20170406}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000378347500091}, doi = {10.1002/2016GL069179}, url = {https://juser.fz-juelich.de/record/810538}, }
