Résumé :

Ozone is a key molecule in atmospheric chemistry. The measurement of this reactive molecule poses a challenge for the scientific community. We will present new precision measurements of the ozone cross sections at 325 nm that resuscitate an old debate about the consistency of currently recommended UV data with IR intensities. Implications of the accuracy of ozone measurements in the Huggins bands are discussed.

We will also report on new measurements of the isotope fractionation in the vis light decomposition of ozone.
