Abstract. Total quenching rate coefficients of Herzberg states molecular oxygen and three triplet nitrogen in the collisions with O2 N2 molecules are calculated on basis quantum-chemical approximations. The electronic O2* N2* show a good agreement available experimental data. An influence collisional processes vibrational populations electronically excited is studied for altitudes high-latitude lower thermosphere mesosphere during auroral electron precipitation. It indicated that metastable...
Abstract. Contributions of intermolecular electron energy transfers in the electronic quenching are calculated for molecular collisions N2(A3Σu+, W3Δu)+N2(X1Σg+, v=0), N2(A3Σu+)+N2(X1Σg+, v≥0), N2(A3Σu+)+O2(X3Σg−, v=0–2), O2(a1Δg, b1Σg+)+O2(X3Σg−, v=0–2). The calculation has allowed one to estimate product branching ratios. It is shown that there a dependence rate coefficients on vibrational excitation N2(X1Σg+) and O2(X3Σg−) molecules. In many cases, have good agreement with available...
A prototype auroral hyperspectral all-sky camera has been constructed and tested. It uses electro-optical tunable filters to image the night sky as a function of wavelength throughout visible spectrum with no moving mechanical parts. The core optical system includes new high power lens F-number equal f/1.1. tested at Kjell Henriksen Observatory (KHO) during season 2011/2012. detects all sub classes aurora above ~½ visual 1kR green intensity threshold an exposure time only one second....
Abstract. Relative vibrational populations of triplet B3Πg, W3Δ,sub>u, B'3Σu− states N2 and the b1Σg+ state O2 are calculated for different altitudes high-latitude upper atmosphere during auroral electron precipitation. It is shown that collisional processes cause a wavelength shift in distribution relative intensities 1PG Δv=3 sequence N2. The calculation levels v=1–5 ionosphere has not given an agreement with experimental results. Preliminary estimation contribution reaction O2++NO to...
Using the experimental rates of O2(b1Σg+, ν=1–3) quenching by oxygen molecules at different temperatures available from literature, estimates were made parameters for analytical formulas which permit calculating constants singlet oxygen. The calculated ν=1–15) and O2(a1Δg, ν=1–20) unexcited T = 300 155 K are in good agreement with data. main channels ν=0–20) ν=0–15) vibrationally excited O2(X3Σg-, ν=1–4) investigated.
Abstract The mechanisms of the production vibrationally excited NO and N 2 molecules at altitudes middle atmosphere Earth during high‐energetic proton precipitation on 20 January 2005 are considered. study vibrational populations (X 1 Σ g + , v ′ > 0) has shown different principal in excitation. First, excitation by secondary electrons is for levels = 1−10. Second, it obtained that intramolecular electron energy transfer process (A 3 u )+N collisions dominates high 20−30. It chemical...
