CANOES II; Dynamics of Atmospheric Infrared Thermochemical Excitation. Volume 3
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, carbon dioxide, and nitric oxide; (2) metastable atomic nitrogen, (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 J thru O pertain to: Production of N2(A3 Sigma (u) (+)) in the Dielectric Barrier (Ozonizer) Discharge; Determination of Non-Boltzmann Vibrational Distributions of N2(X, V ) in He/N2 Microwave-Discharge Afterglows; Quenching Rate Coefficients for N2(a' 1 Sigma (u) (-); Experimental Determination of the Einstein Coefficients for the N2(B-A) Transition; Cochise Operating Manual; and Fluorescence of the W3 Delta(u) Yields B3 Pi(g) and W1 Delta(u) Yields a1 Pi(g) Systems of Nitrogen. Keywords: Infrared emission, Molecular dynamics, Vibrational excitation. (aw)
