Chemicals in gas and oil interact with ozone in the air. This forms Criegee intermediates, which undergo chemical reactions that lead to air pollution. Criegees also can break apart when sunlight hits them. This is because they absorb energy, depending on what wavelength the light is. The absorption spectrum of a Criegee is the amount of energy it absorbs at each wavelength. In this project we got the absorption spectrum by hitting Criegees with bright light and seeing how much the light dims. We also looked at how many Criegees broke apart when hit with light of one wavelength.
This research found the absorption spectrum of the Criegee with the chemical formula CH3CHOO. This is hard because Criegees last a really short time after they are formed (0.001 seconds or less). Also, other things in the air absorb the energy from light, and it's tough to tell them apart from the Criegee absorption. After getting the spectrum, you can figure out how fast Criegees are being degraded in the air. The faster they break apart, the less Criegees are left over that can make air pollution.
