1. The oxidation of an organic material by ozone.

Ozonolysis is the reaction of ozone with an unsaturated hydrocarbon, such as an alkene or alkyne. As the name implies, ozonolysis is ozone-induced bond cleavage. In both alkenes and alkynes, the multiple bond is broken and replaced by a double bond to oxygen, forming a carbonyl compound due to oxidation by ozone.Claus, R.
