Photochemical reaction | chemical reaction | Britannica.com
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.

Photochemical reaction - definition of photochemical ...
photochemical reaction - a chemical reaction produced by the action of light chemical reaction , reaction - (chemistry) a process in which one or more substances are changed into others; "there was a chemical reaction of the lime with the ground water"

Photochemistry - Wikipedia
Photochemical reactions require a light source that emits wavelengths corresponding to an electronic transition in the reactant. In the early experiments (and in everyday life), sunlight was the light source, although it is polychromatic.

What is a Photochemical Reaction? - Definition from ...
A photochemical reaction is a chemical reaction that is initiated when the molecules of a substance absorb light energy. This reaction causes the molecules to undergo a transient excited state, consequently changing their physical and chemical properties from the original molecule of the substance.

A.V. Vähätalo, in Encyclopedia of Inland Waters, 2009 Photochemistry Starts from the Absorption of Solar Radiation. Photochemical reactions of organic matter can take place in surface waters and any irradiated surfaces of organic or inorganic substrata. The prerequisite for photochemical reactions is the absorption of radiation. The photolytic ultraviolet (UV) and short wavelength visible ...

Mechanistic organic photochemistry - Wikipedia
Mechanistic organic photochemistry is that aspect of organic photochemistry which seeks to explain the mechanisms of organic photochemical reactions. [1] [2] The absorption of ultraviolet light by organic molecules very often leads to reactions.

Photochemistry: Theoretical Concepts and Reaction Mechanisms
In the course of a photochemical reaction there is a considerable time interval when the molecular system is out of the thermal equilibrium (a few ps in condensed phase, up to ms in low pressure gas phase reactions).

PHOTOCHEMICAL REACTOR - TECHINSTRO
The photochemical reactor is used to carry out a photochemical reaction, water splitting, and photochlorination reaction. The reaction takes place in the presence of photon and catalyst. Hence it is called as photocatalysis reaction or photochemical reaction.
