Wikipedia
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 thermal 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 is also destructive, as illustrated by the photodegradation of plastics.
Usage examples of "photochemistry".
Granted, the scientific evidence points toward Iapetus being an icy body, the dark half only a thin layer left by an impact or produced by the fierce photochemistry of space.
The reason is that the photochemistry takes place at the interface between the TiO2 and the water, so the more contact area, the better the reactions proceed.
Surprisingly, semiconductor-driven photochemistry was only really figured out in the 1960s.
Anyway, the reason for the delay in understanding semiconductor-driven photochemistry seems to be that it fell through the disciplinary cracks.
An entirely unexpected connection was found between the atmospheric photochemistries of the two planets.
