photochemistry
Radiation-triggered chemical change
Photochemistry is the branch of chemistry dealing with the effects of light on chemical reactions.
Some reactions only occur when light provides energy to trigger them—photography, photosynthesis, and the breakdown of ozone all involve photochemical processes.
The photochemistry of the atmosphere determines how pollutants behave in sunlight.
