AI Article Synopsis
- The study examines the photolysis (light-induced breakdown) of BrCHCHBr or ClCHCHCl in a mixture with NO2 and Ar gas under UV light (wavelengths longer than 240 nm).
- This process resulted in the formation of infrared bands indicating the presence of carbonyls, carbon monoxide, and ketene species.
- No evidence of a precursor complex formation between NO2 and the brominated or chlorinated compounds was detected when these substances were initially deposited.
Article Abstract
Photolyses of matrices of either BrCHCHBr/NO2/Ar or ClCHCHCl/NO2/Ar using quartz-filtered radiation (lambda>240 nm) led to the appearance of infrared bands attributable to carbonyl, carbon monoxide, and ketene species; no bands belonging to a precursor complex NO2cdots, three dots, centeredXCHCHX (where X=Br or Cl) were observed upon matrix deposition. The possible reaction pathway is discussed.
