ClO is also a reactive radical and reacts quickly with another ozone molecule, converting it to two O 2 molecules, and freeing the Cl to do still more damage. ![]() When a chlorine atom encounters an ozone molecule (O 3), it takes one of the oxygen atoms away, leaving O 2 and chlorine oxide (ClO). Radicals are very reactive so chlorine atoms react easily with molecules of ozone. Since the chlorine atom has an unpaired electron, it is a radical. But if CFCs really could reduce ozone at a predicted rate of 7 percent after 60 years, the world would be in trouble.Īccording to Molina’s theory, the same photons from ultraviolet light that break oxygen molecules apart to produce oxygen atoms can also break CFCs apart to release chlorine atoms, among other products. Molina, just a young scientist at the time he did the study, was nervous about talking to Rowland about his theory of how CFCs might destroy ozone. Far above the earth’s surface, in the stratosphere, a thin layer of ozone floats, protecting us from the sun’s ultraviolet radiation. Molina’s study was a hypothetical one based on computer modeling, but his results suggested that CFCs could, in theory, destroy an oxygen compound called ozone under the conditions that exist in the upper atmosphere. Molina wondered what happened to them once they were released into the atmosphere. CFCs were used as refrigerants, aerosol sprays, and in making plastic foams. He had been investigating a class of compounds called chlorofluorocarbons, or CFCs. Sherwood Rowland at the University of California, Irvine, made an unsettling discovery. In 1973 Molina, a postdoctoral researcher working in the laboratory of F. ![]() Once confirmed, however, their findings earned them a Nobel Prize. ![]() In the two decades following his discovery, he and his mentor became voices alerting the world to the danger of CFCs and ozone depletion.
