| Zusammenfassung |
| Total quenching rate coefficients of Herzberg states of molecular oxygen and
three triplet states of molecular nitrogen in the collisions with O2
and N2 molecules are calculated on the basis of quantum-chemical
approximations. The calculated rate coefficients of electronic quenching of
O2* and N2* molecules show a good agreement with
available experimental data. An influence of collisional processes on
vibrational populations of electronically excited N2 and O2
molecules is studied for the altitudes of high-latitude lower thermosphere
and mesosphere during auroral electron precipitation. It is indicated that
molecular collisions of metastable nitrogen N2(A3Σu*) with O2 molecules are principal mechanism in electronic
excitation of both Herzberg states c1Σu&minus, A'3Δu, A3Σu+ and high vibrational
levels of singlet states a1Δg and b1Σg+ of molecular oxygen O2 at these altitudes. |
