R11, R12, and R113, which are stable in ν, have a special mission in the troposphere for a long time and diffuse to reach M81, where the chlorine radicals generated by decomposition by sunlight cause a chain reaction with ozone and destroy the ozone layer. As a result, regulations on the use of these conventional fluorocarbons have been implemented. For this reason, there is active search for alternative fluorocarbons that are less likely to deplete the ozone layer in place of these conventional fluorocarbons.
