Scientific paper

Chemical reactions involving carbon dioxide are prominent in a variety of environments and, therefore, important for modeling reaction pathways and quantifying molecular abundances. In atmospheres and in outer solar system ices, for example, radiation induced degradation of abundant chemical species like ozone, oxygen, carbon dioxide, or molecular nitrogen can liberate high energy oxygen or nitrogen atoms that may react with carbon dioxide. This work presents a study of these reactions where in the carbon dioxide - oxygen atom reaction, two carbon trioxide isomers (C2v and D3h symmetry) were found to form. In the carbon dioxide - nitrogen atom system, the bent OCNO radical was formed. Rate constants have been derived for these reaction pathways and the dynamics of the reactions are investigated.
