Photochemical Reaction: Definition, Examples, & Applications
A photochemical reaction is a chemical reaction that is initiated by the absorption of energy in the form of light (photons), resulting in specific products. Usually, molecules prefer to remain in the state of lowest energy, known as the ground state.
Photochemistry - Wikipedia
Photochemistry is the branch of chemistry concerned with the chemical effects of light. Generally, this term is used to describe a chemical reaction caused by absorption of ultraviolet (wavelength from 100 to 400 nm), visible (400–750 nm), or infrared radiation (750–2500 nm). [1] .
Photochemical reaction | Light-Induced Chemical Changes | Britannica
Photochemical reaction, a chemical reaction initiated by the absorption of energy in the form of light. The consequence of molecules’ absorbing light is the creation of transient excited states whose chemical and physical properties differ greatly from the original molecules.

Photochemistry - Michigan State University
A photochemical reaction occurs when internal conversion and relaxation of an excited state leads to a ground state isomer of the initial substrate molecule, or when an excited state undergoes an intermolecular addition to another reactant molecule in the ground state.
Photochemical Reaction - an overview | ScienceDirect Topics
Section “Mechanisms of photochemical reactions ” explains the mechanistic principles of photochemical reactions. They start from the primary photophysical events, but the following thermal secondary reactions are responsible for chemical transformations.
Photochemical Reactions Definition Types and Examples - Vedantu
A photochemical reaction is a chemical reaction that is initiated by the absorption of light energy (photons). When molecules absorb light, they are promoted to an excited electronic state, which makes them more reactive than in their ground state.
Photochemical Reaction - an overview | ScienceDirect Topics
A photochemical reaction is defined as a chemical reaction that is triggered by the absorption of a photon, whereby a reactant molecule becomes electronically excited and subsequently undergoes a chemical transformation in its excited state, resulting in the formation of a photochemical product.
