Optical Properties and Solubility of Ozone in CCl4 at Low Temperature

Ozone was concentrated in ССl 4 matrix at successive cooling. It has been shown that absorption spectra of ozone in ССl 4 (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 s...

Zusammenfassung:Ozone was concentrated in ССl 4 matrix at successive cooling. It has been shown that absorption spectra of ozone in ССl 4 (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 О 3 –ССl 4 system are independent of temperature. Molar absorptivity of the Chappuis band has been measured (ε 600 8.0±0.3 M –1 cm –1 ), on the basis of which limiting solubility of ozone in the CCl 4 at 760 mmHg has been determined.
