TL;DR: In this paper, a wetted wall flow tube was used to measure the uptake coefficients, γ, of OH and HO 2 on pure water at 275 K and 28% w/w sulfuric acid at 249 K.
Abstract: A wetted wall flow tube reactor was used to measure the uptake coefficients, γ, of OH and HO 2 on pure water at 275 K and 28% w/w sulfuric acid at 249 K. The uptake coefficients are lower limits to the mass accommodation coefficients, α, and the γ were determined to be 0.0035 for OH and >0.01 for HO 2 on liquid water and >0.08 for OH and >0.05 for HO 2 on the sulfuric and solution. In addition, the binary diffusion coefficients for HO 2 and OH in water vapor were estimated to be 79±8 and 116±20 Torr cm 2 s -1 , respectively, at 275 K

TL;DR: In this article, the relative absorption cross sections for the ClOO radical were measured in the region 220-280 nm and the absolute UV absorption cross section at 246.0 nm, the peak of the absorption, was determined to be (2.98±0.23)×10 -17 cm 2 molecule -1.
Abstract: The relative absorption cross sections for the ClOO radical were measured in the region 220-280 nm. The absolute UV absorption cross section at 246.0 nm, the peak of the absorption, was determined to be (2.98±0.23)×10 -17 cm 2 molecule -1 . Using this value, the cross sections in the 220-280-nm range were calculated. The equilibrium constant for the Cl+O 2 ⇄ClOO reaction was measured at six temperatures between 191 and 250 K
