Electronically Excited Atomic and Molecular Oxygen.

Abstract

The rates and mechanisms through which the electronically excited states of oxygen are formed and destroyed in the upper atmosphere have been studied in a discharge flow system. Using a technique in which excited states are formed by surface catalyzed recombination, rate constants have been obtained for the quenching of the O2(A), O2(c) and O (singlet S) states by atmospheric species. the yields of the electronically excited states O2(singlet delta), O2(singlet sigma) and O(singlet S) in atom recombination have been determined directly. Evidence has been found for the existence of a precursor in each of these systems. The rate laws for the formation of O2(A), O2(c) and O(singlet S) have been established and rate constants for some of the elementary steps have been determined by combining these rate laws with the results of quenching experiments.
