ULTRAVIOLET PHOTOLYSIS Meaning and
Definition
-
Ultraviolet photolysis refers to a chemical reaction that occurs when a molecule absorbs high-energy ultraviolet (UV) radiation and undergoes a decomposition or disintegration process. This reaction is predominantly driven by the energy transfer from the absorbed UV photons to the molecular bonds, resulting in the breaking of these bonds and the fragmentation of the molecule into smaller chemical species or radicals.
Ultraviolet photolysis plays a crucial role in various fields, including atmospheric chemistry, environmental science, and photobiology. In the Earth's atmosphere, for instance, UV photolysis of pollutants, such as ozone-depleting substances or volatile organic compounds, leads to the formation of reactive radicals, which can further participate in complex chemical reactions affecting air quality and climate dynamics.
The process of ultraviolet photolysis is highly dependent on factors such as the wavelength and intensity of the incident UV radiation, the chemical composition and structure of the molecule being irradiated, as well as the environmental conditions, such as temperature and pressure. Additionally, the presence of other reactants or catalysts can also influence the efficiency and outcome of the photolysis reaction.
Understanding ultraviolet photolysis mechanisms and studying the kinetics and products of these reactions is essential for elucidating the behavior of chemical species in various environments and for predicting their impact on the environment, human health, and technological processes. Experimental techniques and computational models are commonly employed to investigate ultraviolet photolysis and provide valuable insights into the complex dynamics of molecular decomposition induced by UV radiation.

Etymology of ULTRAVIOLET PHOTOLYSIS
The etymology of the word "ultraviolet photolysis" can be broken down as follows:
1. Ultraviolet: The word "ultraviolet" combines the Latin prefix "ultra-" meaning "beyond" or "on the other side of" and the word "violet", which refers to a color in the visible light spectrum. The term was first coined in the late 19th century by the German physicist Johann Wilhelm Ritter to describe electromagnetic radiation beyond the violet end of the spectrum.
2. Photolysis: The word "photolysis" is derived from the Greek roots "photo-" meaning "light" and "-lysis" meaning "loosening" or "splitting". It refers to a chemical reaction or decomposition caused by light energy. The term was introduced in the early 20th century by German chemist Franz Fischer.
