PHOTOCHEMICAL REACTIONS

In photochemical reactions, absorption of ULTRAVIOLET AND VISIBLE radiations takes place.

FEATURES OF PHOTOCHEMICAL REACTIONS:

* A photochemical reaction is a chemical process that is triggered by the absorption of light energy. The absorption of light by molecules results in the formation of transitory excited states with chemical and physical characteristics that are very different from the original molecules.

* UV light that passes through the ozone layer damages DNA photochemically, causing mutations in its replication, which can lead to skin cancer.

* These new chemical species can disintegrate, alter structure, join with other molecules, or transmit electrons, hydrogen atoms, protons, or electronic excitation energy to other molecules. The excited states are more powerful acids and reductants than the ground states.
