Photolysis

4 ClOOCl + hv -- ClO + ClO so the rate of photolysis, which is proportional to the absorption cross-section, determines how much ClO is available for the cycle. ❋ EliRabett (2009)

Another way to initiate some reactions rapidly is flash photolysis, i.e. by short light flashes, a method developed by Ronald G.W. Norrish at Cambridge and George ❋ Unknown (2010)

Double boxes are stable species and the arrows represent photolysis. ❋ Unknown (2010)

Oil floating at the ocean's surface has a limited lifespan - it's been collected and destroyed by skimming, booms, chemical dispersants, evaporation, photolysis, biodegradation - and took a beating from wind and waves when tropical depression Bonnie blew through over the weekend. ❋ Unknown (2010)

It does not depend on the photolysis rate for the CFCs, only on the observed halogen loading and measured reaction rates. ❋ EliRabett (2010)

The flaw in the conventional approach is that only gas-phase chemical reactions and reactions induced by solar radiation photolysis are considered. ❋ Unknown (2009)

In the stratosphere, the source gases are converted through photolysis and reaction with the hydroxyl radical to inorganic species of bromine, chlorine, and fluorine. ❋ Unknown (2009)

They then generated OH, by photolysis of acetone at 280 nm followed by its reaction with O2 to form OH ❋ EliRabett (2009)

Despite this low efficiency, the rate of OH production from NO2* in urban atmospheres can be comparable to the classical OH source ozone photolysis. ❋ EliRabett (2009)

In addition, oil degrades at varying rates depending on environment, with subsurface sediments physically protected from disturbance, oxygenation, and photolysis retaining contamination by only partially weathered oil for years. ❋ Unknown (2008)

In actuality, I spent my time learning to blow glass and construct vacuum lines, and to measure low concentrations of photolysis products using a temperamental, delicate, almost impossible to align, multi-pass Perkin-Elmer IR machine connected to a vacuum line. ❋ Unknown (2006)

Put in a high enough rate of photolysis for chloral in your simulation and you can get the whole system to react. ❋ James Killus (2008)

With a high rate of photolysis for chloral, the simulation kicked off too quickly. ❋ James Killus (2008)
