WebOzone is extremely valuable since it absorbs a range of ultraviolet energy. When an ozone molecule absorbs even low-energy ultraviolet radiation, it splits into an ordinary oxygen molecule and a free oxygen atom. Usually this free oxygen atom quickly re-joins with an oxygen molecule to form another ozone molecule. WebSep 1, 2016 · Furthermore, O 3 absorption cross-sections are required over a large spectral range: in the ultraviolet–visible region, ozone absorbs at all wavelengths between 200 and 1100 nm covering a very large dynamic range: the highest absorption of about 10 −17 cm 2 molecule −1 is observed at the peak of the Hartley band around 250 nm, while the … labor boots https://daria-b.com
