Dissociation of iodine molecules and singlet oxygen generation in O-2 - I-2 mixture induced by 1315-nm laser radiation

摘要

It is observed that laser light at a wavelength of 1315 nm induces continuous stable fluorescence at the O-2(b (1)Sigma -> X (3)Sigma) and I-2(B (3)Pi(u) -> X (1)Sigma) bands in a O-2 - I-2 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 O-2(a (1)Delta), O-2(b (1)Sigma), and I-2(B (3)Pi(u)) molecules in the O-2 - I-2 mixture under irradiation at 1315 nm.
