Hydrogen ozonide explained

Hydrogen ozonide is a radical molecule consisting of a hydrogen atom covalently bonded to an ozonide unit.^[1]

It is possibly produced in the reaction of the hydroxyl radical with dioxygen: OH^• + O₂ → HO₃^•.^{[2] [3]}

It has been detected in a mass spectrometer experiment using (protonated ozone) as precursor.^[4]
