Photodissociation of Molecular Oxygen (O2)

Photodissociation of oxygen.
Animation courtesy COMET.

This animation illustrates the process of photodissociation of oxygen. When an extreme ultraviolet (EUV) photon strikes an oxygen molecule, it photodissociates the molecule into two separate oxygen atoms. The energy from the photon breaks the chemical bond that holds the molecule together. The result is two separate oxygen atoms.

You will need to have the latest version of the Flash player to see this animation.
