Optical Properties and Solubility of Ozone in CCl4 at Low Temperature

Resumo

Ozone was concentrated in ССl₄ matrix at successive cooling. It has been shown that absorption spectra of ozone in ССl₄ (λ_max 258 nm) are practically identical to these in an aqueous solution. Vibrational structure typical of gaseous ozone over the Chappuis range has been retained. Position and shape of the bands for the О₃–ССl₄ system are independent of temperature. Molar absorptivity of the Chappuis band has been measured (ε₆₀₀ 8.0±0.3 M^–1 cm^–1), on the basis of which limiting solubility of ozone in the CCl₄ at 760 mmHg has been determined.
