Past work in polyethylene has shown the yield strength to obey a simple empirical temperature/strain-rate equivalence law, with one-decade increase in strain-rate approximately equivalent to a 10 K drop in temperature.
Thus, the photochemical equivalence law is restated as: for every mole of a substance that reacts 6.022140857 × 1023 quanta of light are absorbed.
The photochemical equivalence law is also sometimes called the Stark Einstein law after the German-born physicists Johannes Stark and Albert Einstein, who independently formulated the law between 1908 and 1913.
Photochemical equivalence law, fundamental principle relating to chemical reactions induced by light, which states that for every quantum of radiation that is absorbed, one molecule of the substance reacts.
The photochemical equivalence law applies to the part of a light-induced reaction that is referred to as the primary process; that is, the initial chemical change that results directly from the absorption of light.
Implicit in the previous sentence is the photochemical equivalence law, also called the Stark-Einstein law, which states that a single molecule may absorb exactly one photon of light.
Von't Hoff first used the osmotic measurements from Pfeffer, De Vries, Hamburguer, Donders and Raoult to suggest the theoretical and experimental equivalence between the laws of ideal gases and those that ruled the behavior of dilute solutions [ 77, 78].
Equivalence principle, fundamental law of physics that states that gravitational and inertial forces are of a similar nature and often indistinguishable.
Equivalence, in the patent law, is not the prisoner of a formula and is not an absolute to be considered in a vacuum.
