When in a liquid state and pressurized, they are useful as solvents in infrared spectroscopy.
In the early 1990s, chemists at Yale discovered that five members of this group can be trapped at the center of a buckminsterfullerene molecule. When in a liquid state and pressurized, they are useful as solvents in infrared spectroscopy. They are also used to fill spark chambers. Their name is not wholly accurate, as the hexafluoroplatinate of one was created in 1962. FTP, give the common name for elements of group O such as krypton, argon, and helium.
