Humans rely on photochemistry for the formation of vitamin D, and vision is initiated by a photochemical reaction of rhodopsin.
22.
For example, some organic dye molecules can undergo a photochemical reaction, which alters the whole chemical structure of the molecule.
23.
Human-made smog is derived from coal emissions, vehicular emissions, industrial emissions, forest and agricultural fires and photochemical reactions of these emissions.
24.
They enclosed samples of gas in a quartz tube, which was subjected to an intense flash of light which caused photochemical reactions.
25.
Over the decades, many interesting but puzzling organic photochemical reactions were discovered that did not proceed by ordinary organic ground state processes.
26.
Another application of the photoacoustic effect is its ability to estimate the chemical energies stored in various steps of a photochemical reaction.
27.
Porter went to Cambridge in 1945 as a postgraduate research student with Norrish, studying the production of free radicals in gaseous photochemical reactions.
28.
The cone cells, responsible for color vision, probably respond to frequency, rather than wavelength, because the detection of light is a photochemical reaction.
29.
Researchers aimed to utilize the hydrophobic environments of the dendritic media to conduct photochemical reactions that generate the products that are synthetically challenged.
30.
Methane dissociates in the atmosphere through photochemical reactions-for instance it reacts with hydroxyl ions forming water and CO 2 in the presence of sunlight.
