Abstract:
It is observed that laser light at a wavelength of 1315 nm induces continuous stable fluorescence at the O2(b 1Σ → X 3Σ) and I2(B 3Πu → X 1Σ) bands in a O2–I2 mixture preliminarily irradiated at a wavelength of 532 nm to achieve partial photolysis of iodine molecules. This testifies to generation of iodine atoms and excited O2(a 1Δ), O2(b 1Σ), and I2(B 3Πu) molecules in the O2–I2 mixture under irradiation at 1315 nm.
Keywords:fluorescence, laser radiation, singlet oxygen, iodine, dissociation.
