Time-resolved Raman observation of the aqueous O 3
A Raman study of the O −+O 2→O 3 − reaction in aqueous solution is reported. The reaction half-period was measured as ∼ 200 ns in oxygen saturated solution at room temperature. Spectroscopic evidence for the O 3 −-solvent coupled vibrations has been found. The harmonic frequency ( Ω e ) of the O 3 −...

− reaction in aqueous solution is reported. The reaction half-period was measured as ∼ 200 ns in oxygen saturated solution at room temperature. Spectroscopic evidence for the O

−-solvent coupled vibrations has been found. The harmonic frequency (
Ω

) of the O
3
− symmetric stretch in aqueous solution, 1058 cm
−1, is 30–40 cm
−1 higher, and the anharmonicity constant (
Ω

), 9 ± 2 cm
−1, about twice as large as compared to the O
3
−1 inbedded in crystalline matrices or bonded to a counter ion. The O
3
−→2O+O
− dissociation energy is drastically lowered on hydration. |
