Beschreibung:
<jats:p>Flash photolysis of O3 in the Hartley band has been coupled with absorption spectroscopic detection of O2(1Δ, v=0) and resonance fluorescence detection of O(3P) to analyze the fate of O2(1Δ, v?1) in an atmospheric environment. The results indicate a rapid vibrational deactivation under atmospheric conditions. The same analysis permits an estimate of the relative quantum yield of O2(1Δ, v?1) in the photolysis. Similarly, an upper limit for the channel of the O(1D)+O3 reaction yielding O2(1Σ) is derived.</jats:p>
