Atmospheric Trioxy Radical Idea Banished

Transient fusing of O2 and ·OH to form ·HO3 doesn’t seem to be important in atmospheric chemistry
Department: Science & Technology
Keywords: atmosphere, hydroxyl radical, hydrogen trioxy radical, HOOO

For years, scientists have tried to determine if a transient fusing of molecular oxygen and the hydroxyl radical (·OH) plays a significant role in atmospheric chemistry. Sébastien D. Le Picard of the University of Rennes, in France, and colleagues say they have the answer: No (Science 2010, 328, 1258). Experiments and theory have both suggested that ·OH, which acts as a chemical mop to sweep up many atmospheric pollutants, could be temporarily sequestered . . .
