The absolute efficiencies for the vibrational excitation of molecules which quench singlet molecular oxygen have been determined from measurements of their infrared chemiluminescence and kinetics of relaxation. The systems studied were NO and CO with O 2 ( 1 ∆ g ) and NO, CO, HCl, DCl, H 2 O, D 2 O, CO 2 , N 2 O, NH 3 and C 2 H 2 with O 2 ( 1 ∑ + g ). Rate coefficients for the vibrational relaxation of a number of these molecules by molecular oxygen were also determined.

Quenching studies have been made in a spherical vessel containing known concentrations of O 2 ( 1 ∆ g ) and O 2 ( 1 ∑ + g ). Rate coefficients for the quenching of O 2 ( 1 ∆ ) by CO and of O 2 ( 1 ∑) by N 2 O, D 2 O, NH 3 , C 3 H 8 , C 2 H 2 , HCl and DCl have been determined. Efficient wall deactivation of O 2 ( 1 ∆) by adsorbed hydrogen halides was observed.

We study the electronic kinetics of molecular nitrogen and molecular oxygen in the middle atmosphere of the Earth during precipitations of high-energetic protons and electrons.The role of molecular inelastic collisions in intermolecularelectron energy transfer processes is investigated.It is shown that inelastic molecular collisions influence on vibrational populations of electronically excited molecular oxygen. It is pointed out on very important role of the collisions of N2(A3u+) with O2molecules on the electronic excitation of Herzberg states of molecular oxygenat the altitudes of the middle atmosphere.

Abstract. 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.
