Abstract
The spectroscopy and kinetics of reactive intermediates in the atmospheres of Venus, Earth, and Mars were investigated through a combination of experimental and theoretical methods. Vibrational progressions in the A- and B-bands of ClSO were assigned, and predicted spectra matched well with experiment. A new unimolecular mechanism for 3-hydroxy-substituted Criegee intermediates was proposed, and predicted to be competitive with known isomerization pathways. The kinetic isotope effect and temperature dependence of the H + HO₂ reaction was calculated using high-level ab initio methods, with implications for the understanding of water loss on Mars.
