TL;DR: The impact of new laboratory data for the reaction BrO + HO2 → HOBr + O2 has been estimated in a one-dimensional photochemical modelling of bromine/ozone stratospheric chemistry.

TL;DR: In this article, the authors used discharge-flow mass-spectrometric method to study the kinetics of the reaction of chlorine atoms with isoprene and found that the overall rate constant k1 = (67 ± 20) × 10-11 exp{(485 ± 85)/T} cm3 molecule-1 s-1 was obtained at a pressure of 1 Torr of helium over the temperature range 233−320 K k1 was found to be pressureindependent (within 10%) at T = 298 K in the pressure range 025−3 Torr in the

TL;DR: In this article, the reaction of ozone with toluene and kerosene flame soot was studied over the temperature range 240 to 350 K using a low pressure (a few Torr) flow reactor coupled to a modulated molecular beam mass spectrometer.

TL;DR: In this paper, a high-pressure turbulent flow reactor coupled with an ion molecule reaction mass spectrometer was used to study the reactions of OH radicals with dimethyl sulfoxide (CH3)2SO (DMSO) and methane sulfinic acid CH3S(O)OH (MSIA) (reaction 2) at 298 K and 200 and 400 Torr of N2.

TL;DR: The pressure and temperature dependence of beta was determined in the pressure range of 72-600 Torr of N(2) carrier gas between 323 and 223 K, and at each pressure, the branching ratio was found to increase with the decrease of temperature, the increase becoming less pronounced with the increase of pressure.
