| Popis: | The self-quenching kinetics of O2(1Δ) molecules in the O2 — O2(1Δ) — H2O gas mixture produced by a chemical singlet-oxygen generator for an oxygen—iodine laser is investigated. The rate of change in the O2(1Δ) concentration in continuous-flow tube is determined by measuring the absolute spectral irradiance of the O2 — O2(1Δ) — H2O gas mixture in the ranges of 600 — 800 nm and 1210 — 1330 nm. The effective rate constant of O2(1Δ) deactivation in all possible channels of the O2(1Δ) + O2(1Δ) → products reaction is found to be (8±1.2)×10-17 cm3 s-1. |
