Among the gases formed are hydrogen fluoride (HF), phosphoryl fluoride (POF3) and phosphorus pentafluoride

trifluoride(N[F.sub.3]), and trifluoromethyl sulfur pentafluoride
Few people can easily pronounce trifluoromethyl sulfur pentafluoride
, much less figure out what it is.
The gas, known as SF5CF3 (trifluoromethylsulphur pentafluoride
), is found mostly in the upper atmosphere between 5 and 20 miles high, where it traps heat radiating from the Earth's surface.
The researchers find the gas, trifluoromethyl sulfur pentafluoride
([SF.sub.5][CF.sub.3]), only at trace levels--about 0.12 parts per trillion in 1999--in the atmosphere, but their analysis shows that concentrations are rising at about 6 percent per year.
Moreover its acidity can be still further increased by the addition of a pentafluoride
such as [SbF.sub.5] to values as high as [-H.sub.0] = 25 [5,6,7].
