1. Photochemistry

   Photochemistry is the branch of chemistry concerned with the chemical effects of light. Generally, this term is used to describe a chemical reaction caused by absorption of ultraviolet (wavelength from 100 to 400 nm), visible light (400–750 nm) or infrared radiation (750–2500 nm).In nature, photochemistry is of immense importance as it is the basis of photosynthesis, vision, and the formation of vitamin D with sunlight. Photochemical reactions proceed differently than temperature-driven reactions. Photochemical paths access high energy intermediates that cannot be generated thermally, thereby overcoming large activation barriers in a short period of time, and allowing reactions otherwise inaccessible by thermal processes. Photochemistry can also be destructive, as illustrated by the photodegradation of plastics.

1. photochemistry

   Photochemistry is the branch of chemistry that involves the study of chemical reactions, processes and mechanisms that are instigated by light or other forms of electromagnetic radiation. It explores how molecules and atoms absorb photons from light and undergo chemical transformations into other molecules. Example applications include photosynthesis, vision and photography.

Examples of photochemistry in a Sentence

1. Kelly Miller:

   Because Titan is the only moon in our solar system with a substantial atmosphere, scientists have wondered for a long time what its source was, the main theory has been that ammonia ice from comets was converted, by impacts or photochemistry, into nitrogen to form Titans atmosphere. While that may still be an important process, it neglects the effects of what we now know is a very substantial portion of comets: complex organic material.
