RELATIVE EINSTEIN COEFFICIENTS AND DIPOLE-MOMENTS OF THE O-2 (A(3)SIGMA(-]CHI-(3)SIGMA(-)(G), UPSILON'', C-(1)SIGMA(-)(U), UPSILON'-]CHI-(3)SIGMA(-)(G), UPSILON'') TRANSITIONS MEASURED IN OXYGEN-ATOM RECOMBINATION ACCOMPANIED BY RADIATION()(U), UPSILON'')

Spectra accompanying oxygen atom recombination have been measured in t he 280-600 nm spectral range, at all-O-2 and approximately all-He and all-N-2 baths with 2 nm spectral resolution and an accuracy of several per cent. Emission bands from the O-2(A (3) Sigma(u)(+), upsilon' = 0 -4 and c (1) Sigma(u), upsilon' = 0, 1) vibronic levels have been obse rved and assigned by a simulation procedure. Intensities of individual bands, relative Einstein coefficients, relative transition moments an d vibronic level populations have been determined. The population prof iles of the A (3) Sigma(u)(+), upsilon' = 0-4 and c (1) Sigma(u), upsi lon' = 0, 1 vibronic levels depend strongly on the relative O-2 concen tration. A nonmonotonic dependence of the c (1) Sigma(u)(-)-X (3) Sigm a(g)(-) transition moment with internuclear distance in its 0.136-0.15 3 nm range has been found. The mechanism and kinetics of population an d decay of vibronic levels of the molecular oxygen ungerade states and night airglow on Earth and Venus are discussed.
