Fotonilisi

Fotonilisi is a term that can refer to several related phenomena involving light and molecular decomposition. Primarily, it describes the breakdown of a molecule into smaller components due to the absorption of light energy, specifically photons. This process is a type of photochemistry, where light drives a chemical reaction. The energy of the absorbed photon must be sufficient to overcome the bond energies within the molecule, leading to bond cleavage.

In a broader sense, fotonilisi can also be used to describe the degradation of materials, such as plastics or pigments, when exposed to ultraviolet (UV) radiation from sunlight. This photodegradation can alter the color, strength, and overall integrity of the material. The specific wavelengths of light involved and the nature of the bonds being broken determine the products of fotonilisi. Understanding fotonilisi is crucial in fields ranging from atmospheric chemistry, where it explains the breakdown of pollutants, to materials science, where it informs the development of light-stable products. It is a fundamental process in many natural and artificial systems.
