| Popis: | The method of intracavity laser spectroscopy using a Co:MgF2 laser is applied to record the absorption spectra from the first excited a1Δg state of gaseous molecular oxygen at the a1Δg → b1Σg+ transition at 1.91 μm. The gas flow from a chemical singlet oxygen generator with a known concentration of singlet oxygen O2 (a1Δg) was supplied to the cavity of the Co:MgF2 laser. The absorption line intensities are measured for five spectral lines of the Q-branch of the 0–0 vibrational band for the a1Δg → b1Σg+ transition. The O2 (b1Σg+ → a1Δg) transition probability calculated from these data was (1.20 ± 0.25) × 10-3 s-1. |
