In a light-catalyzed reaction, chlorine radicals break up this compound, which normally absorbs UV radiation in the stratosphere.
This compound's presence can be quantified in spectrophotometry by observing an intense absorption peak at 255 nanometers; that peak is the Hartley band. Fluoroelastomers like Viton are useful in chemical-resistant gloves because they are resistant to cracking upon reaction with this compound; that cracking reaction, which is performed in the laboratory using a methanol or dichloromethane solvent at negative 78Â degrees Celsius, is a 1,3-dipolar (*) cycloaddition in which this compound cleaves alkenes. The Dobson unit was formulated to measure the concentration of this compound. In a light-catalyzed reaction, chlorine radicals break up this compound, which normally absorbs UV radiation in the stratosphere. For 10 points, a namesake "hole" in the Antarctic is deficient in what compound with formula O3?
