Input: Consider Input: This molecule facilitates the Griesbaum reaction and cleaves an alkene to forms an aldehyde or a ketone in a 1,3 dipolar cycloaddition, the Criegee mechanism. In the Chapman Cycle, this diamagnetic compound with a bent geometry is replenished by a paramagnetic, diatomic molecule. In that reaction, this molecule is formed by the absorption of a photon with a wavelength of less than 280 nanometers. It can be depleted by chlorofluorocarbons, making the Earth more susceptible to ultraviolet radiation. For 10 points, name this molecule found in a namesake atmospheric "layer", a triatomic allotrope of oxygen.
