photochemical reaction उदाहरण वाक्य

उदाहरण वाक्य

1. Specifically Michler s ketone absorbs intensely at 366 nm and effectively sensitizes photochemical reactions such as the dimerization of butadiene to give 1, 2-divinylcyclobutane.
2. He was the first to use two lasers to follow photochemical changes in short-lived intermediates during a reaction which allows scientists to measure photochemical reactions.
3. Photochemical reactions are initiated by the absorption of a photon, typically in the wavelength range 290-700 nm ( at the surface of the Earth ).
4. Worldwide, the largest source of carbon monoxide is natural in origin, due to photochemical reactions in the troposphere that generate about 5 kilograms per year.
5. In most photochemical reactions the primary process is usually followed by so-called secondary photochemical processes that are normal interactions between reactants not requiring absorption of light.
6. Still another type of photochemical reaction is the di-pi-methane rearrangement . " Unsymmetrical Substitution and the Direction of the Di-pi-Methane Rearrangement; Mechanistic and Exploratory Organic Photochemistry.
7. This cycle is often a cause of smog through photochemical reactions that occur when strong concentrations of the pollutants in this cycle are exposed to solar radiation.
8. During the spring, however, the sun comes out, providing energy to drive photochemical reactions and melt the polar stratospheric clouds, releasing considerable ClO, which drives the hole mechanism.
9. Furthermore, photoacoustic measurements serve as a valuable research tool in the study of the heat evolved in photochemical reactions ( see : photochemistry ), particularly in the study of photosynthesis.
10. In 1906 he received a Ph . D from the University of Leipzig for research at the Institute for Physical Chemistry, led by Wilhelm Ostwald on the kinetics of photochemical reactions.
