For the reaction of O(1D) and N2O,

For the reaction of O(1D) and N2O, three pathways, can be conceived. Although the formation ratio of O(3P) by reaction (5.16) is 0.01 and can be neglected in general (Vrackx et al, 2008a), the reaction pathways, (5.14) and (5.15), are known to be both important. In atmospheric chemistry, reaction (5.15) is important as the formation of reactive nitrogen (also called odd nitrogen) in the stratosphere, and the overall reaction rate constant combining reaction (5.14) and (5.15) is important for the estimation of atmospheric lifetime of N2O.
