Gas phase atmospheric bromine photochemistry
This paper reviews the current knowledge of gas phase bromine photochemistry and presents a budget study of atmospheric bromine species. The effectiveness of the ozone catalytic loss cycles involving bromine is quantified by considering their chain length and effectiveness. The chain effectiveness i a new variable defined as the chain length multiplied by the rate of the cycle's rate-limiting s...
متن کاملAtmospheric Sulfur Photochemistry on Hot Jupiters
We develop a new 1D photochemical kinetics code to address stratospheric chemistry and stratospheric heating in hot Jupiters. Here we address optically active S-containing species and CO2 at 1200 ≤ T ≤ 2000 K. HS (mercapto) and S2 are highly reactive species that are generated photochemically and thermochemically from H2S with peak abundances between 1-10 mbar. S2 absorbs UV between 240 and 340...
متن کاملAtmospheric photochemistry: roaming in the dark.
for the conversion of dinitrogen into ammonia, by demonstrating that ammonia is directly obtained from the nitrido species. The reactivity of the transitionmetal–nitrido complexes described in their papers shows a real advance towards developing a ‘post-Haber–Bosch process’: a synthetic method for the catalytic formation of ammonia from molecular dinitrogen under mild reaction conditions. These...
متن کاملNumerical Simulation of Atmospheric Photochemistry in a Laminar-Flow Tube Reactor
The climatological impact and chemical characteristics of atmospheric aerosols remain very uncertain. The latest step in this field is the experimental use of UV-lit gas-phase tube reactors to simulate days to weeks of atmospheric photochemistry. These reactors have typically been modeled as plug-flow reactors. We have constructed a more detailed model to describe the new laminar-flow tube reac...
متن کاملThe role of photochemistry in Titan s atmospheric chemistry
Experimental studies were performed to simulate the action of long wavelength solar UV light on Titan s atmosphere. The experiments were carried out in a photochemical flow reactor using a mixture of gases representative of Titan s atmosphere at 70 north latitude (Titan s north pole) in the winter. The solid analog of Titan s haze formed has optical properties comparable to that determined for ...
