Outline of Final Research Achievements |
We have studied molecular level mechanism underlying reactions of the superoxide radical anion by exploiting gas-phase cluster reactions and photoelectron spectroscopy, which provide unique access to detailed characterization of product and intermediate anions in the relevant superoxide processes. Two types of reaction systems were investigated: for the reaction with sulfur dioxide, we have proven the existence of a new reaction pathway leading to the formation of sulfate radical anion, while for the reaction with nitric oxide and carbon dioxide, we have spectroscopically identified nitrosoperoxycarbonate, which has long been supposed to play the role of an intermediate to produce the carbonate radical anion in biological environments.
