Popis: A comparison has been made of the value of the rate constant for the simultaneous “dimol” emission of O2(1Δg), calculated from the absorption spectrum, with those from emission measurements. It is suggested that the emitting (O2)2 species has D2h symmetry and that the transition is 1B2u-1Ag. The best value is k = (3.3 ± 0.6) × 10−2 dm3 mol−1 s−1 at 295 K. The temperature dependence is also discussed.
