CANOES 2: Dynamics of Atmospheric Infrared Thermochemical Excitation. Volume 4
Abstract
In the electron disturbed upper atmosphere, electronically excited metastable forms of oxygen and nitrogen are formed by electron impact processes. These species dissipate their energy into the atmosphere largely by collisional quenching and chemical reaction. Specific species and reactions of interest include: 1) electronically and/or vibrationally excited nitrogen, N2*, its spectroscopy, energy pooling and interactions with oxygen, O2 and trace, infrared-active atmospheric species such as carbon monoxide, and carbon dioxide; 2) metastable atomic nitrogen, N(2D, 2P), reaction kinetics and product branching ratios in interactions with the above atmospheric species; 3) various metastable states of O2, O2*, and their potential as auroral precursors of infrared radiation from other atmospheric species; and 4) the role of metastable-metastable O2/N2 interactions as potential sources for non-linear infrared effects which might occur in strong aurorae. Appendices P thru U pertain to: Rovibrational Excitation of Nitric Oxide in the Reaction of O2 with Metastable Atomic Nitrogen, Rovibrational Excitation of Carbon Monoxide By Energy Transfer From Metastable Nitrogen, Classical Trajectory Study of Ozone Recombination Dynamics: The Chaperon Mechanism; Formation and Stabilization Dynamics of Ozone Complexes; Multicollisional Trajectory Studies of Vibrationally/Rotationally Excited Ozone Molecules by Argon Atoms, Relaxation of Vibrationally Excited Oxygen Molecules by Collision with Oxygen Atoms. Keywords: Infrared emission, Molecular dynamics. (AW)
