Photolysis is defined as the decomposition of substances on exposure to light, while photooxidation is the oxidation of a substance on exposure to light. Irradiation of tryptophan with UV light results in the formation of a tryptophan radical and a hydrated electron.
Photolysis is the process by which a photochemical reaction is conducted. The immediate outcome of light absorption is a primary photochemical reaction. Secondary reactions are termed subsequent chemical shifts.
- Photodissociation, photolysis, or photodecomposition is a chemical reaction where photons break down a chemical compound.
- It is defined as one or more photons interacting with a single target molecule.
- There is no limited photodissociation to visible light.
Listed below are examples of photolysis
- Photolysis of water in the presence of sunlight is the breakdown of the water molecule into hydrogen and oxygen.
- The process of photosynthesis in which plants convert carbon dioxide and water into glucose and oxygen using solar energy.
- Production of vitamin D in the human body on exposure to sunlight.
- An enzyme in the abdomen catalyses a light-producing reaction in fireflies.
