Photodissociation of Molecular Oxygen (O2)

Photodissociation of oxygen.
Animation courtesy COMET.

This movie shows how an ultraviolet (UV) photon can break apart an oxygen molecule. When the photon hits the oxygen molecule, it adds energy to the molecule. The extra energy breaks the bond between the two oxygen atoms, and the atoms fly apart. This is called photodissociation.

You need the latest version of the Flash player to see this movie.

Photon

Light is very strange. Sometimes it is best to think of light as a series of waves. At other times, it is useful to think of light as a swarm of particles. When we think of light as particles, we call...more
