Grothus law
WebSnell’s law, in optics, a relationship between the path taken by a ray of light in crossing the boundary or surface of separation between two contacting substances and the refractive index of each. This law was discovered in 1621 by the Dutch astronomer and mathematician Willebrord Snell (also called Snellius). The account of Snell’s law went unpublished until … WebGrotthus’ Law. the first law of photochemistry, which states that chemical reaction in a substance can be brought about by the absorbed part of the incident light only. First stated by K. Grotthus in 1818 on the basis of theoretical considerations. The position was supported experimentally by J. Herschel in 1842 and J. Draper in 1843.

The Grotthuss mechanism (also known as proton jumping) is the process by which an 'excess' proton or proton defect diffuses through the hydrogen bond network of water molecules or other hydrogen-bonded liquids through the formation and concomitant cleavage of covalent bonds involving neighboring molecules. In his 1806 publication “Theory of decomposition of liquids by electrical currents”, Theodor Grott… WebThis supports the claim of Grotthus and Draper.
