Jul 16, 2025 · Water has been mistakenly labeled as HO2 (hydroperoxyl radical) in a noted scientific publication. This error is a misrepresentation of the molecular identity of water (H2O) and has …

The hydroxyl radical, OH, initiates the removal of the majority of trace gases in the atmosphere, and together with the closely coupled species, the hydroperoxy radical, HO2, is intimately involved in the …

Sep 15, 2023 · During the summer of 2016, OH, HO2, and RO2 radical concentrations were measured as part of the Program for Research on Oxidants: Photochemistry, Emissions, and Transport – …

Hydroperoxyl (HO₂•) constitutes an inorganic oxygen-centered radical of considerable importance in both atmospheric and chemical processes. This reactive species, also known as hydrogen …

Energy separation between the v = 0 levels of the excited and electronic ground states. Energy separation between the band maximum of the excited electronic state and the v = 0 level of the …

Hydroperoxyl radical (HO2) is amongst the most common HOx radicals in the atmosphere. Hydroperoxyl radical is one of the important oxidising agents in the Earth's atmosphere, biological systems, and …

Jul 6, 2023 · In the atmosphere, photolysis of formaldehyde generates H and HCO radicals, which then react with O2 to form HO2 (important in converting atmospheric carbon to CO2).

HO2*, usually termed either hydroperoxyl radical or perhydroxyl radical, is the protonated form of superoxide; the protonation/deprotonation equilibrium exhibits a pK (a) of around 4.80. …
