N2 - The photogeneration of singlet oxygen O2(a1Δg) resulted from the photoexcitation at 248 nm of gaseous oxygen at elevated pressure (3-80 atm) has been investigated. Singlet oxygen monitored by its IR-luminescence at 1.27 μm was found to appear via two processes which are identified to be due to absorption of individual O2 molecules and encounter complexes O2-O2, respectively. The one-quantum absorption of complexes gives rise to appearance of oxygen in Herzberg III state O2(3Δu) which is supposed to be a triplet sensitizer responsible for singlet oxygen O2(a1Δg) production observed in our experiments. © 2009 Elsevier B.V.
