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].
