ABSTRACT The uptake coefficient(γ) of HO2 for submicrometer aerosol particles of levoglucosan and polystyrene latex (PSL) under ambient conditions (760 Torr and 296 ( 2 K) have been investigated using an aerosol flow tube (AFT) coupled with a chemical conversion/laser-induced fluorescence (CC/LIF) technique. Determined γ values for levoglucosan particles were
