What does photolysis mean?
Photolysis refers to the breakdown of molecules using light energy, often resulting in chemical reactions. This process is crucial in various natural phenomena, such as photosynthesis, and has numerous industrial applications. Photolysis involves the absorption of light by a molecule, leading to its fragmentation or transformation into new compounds. Understanding photolysis is essential in fields like chemistry, biology, and environmental science, as it helps researchers develop new technologies and better comprehend natural processes. The term is widely used in formal and technical contexts.
nounPhotolysis is a chemical reaction in which a molecule is broken down into smaller fragments using light energy. This process is often used in chemistry and biology to initiate reactions.
- A chemical reaction in which a molecule is broken down into smaller fragments using light energy.
- The process of using light to initiate a chemical reaction.
"The photolysis of water molecules in photosynthesis produces oxygen and hydrogen ions."
"The photolysis of ozone molecules in the stratosphere leads to the formation of oxygen."
"Photolysis is used in some industrial processes to break down pollutants."
