Photochemistry

(study of the chemical effects of light)

Photochemistry is the branch of chemistry concerned with chemical reactions caused by Absorption of Visible Light, Ultraviolet (UV), and Infrared (IR). The basic mechanism is absorption of a photon by an atom bringing it to a higher excited state, i.e., an electron is energized to take a higher orbit.
