Sulphur hexafluoride, SFg

The mixing of 3s, three 3p and two 3d orbitals as in sulphur atom in the molecule sulphur hexafluoride SFg is an example of spM hybridization. 

Aluminium is used for protecting underground and undersea telephone cables and for the construction of sulphur hexafluoride (SFg) insulated, sealed converters, where it provides protection from electrical or magnetic fields (hardening). 

The third link between lasers and chemistry is the initiation and control of chemical change in a given system. The initiation of chemical processes by laser radiation has become a powerful area, not only in modern photochemistry, but also for technological applications. An example within this category is the multiphoton dissociation of SFg (sulphur hexafluoride) by IR laser radiation this provides a means by which the two isotopomers and " SFe can be separated. 

Greenhouse gases CF4 (tetrafluoromethane), CjF (hexafluoroethane) and SFg (sulphur hexafluoride) < 500 ppb... 

Sulphur, selenium and tellurium all form the hexafluoride by direct combination other hexahalides are unknown. SFg and SeFg are chemically inert, colourless gases. The former is non-toxic and at once the most inert sulphur compound and possibly the most inert non-ionic fluorine compound it resists fused KOH. The somewhat more reactive SeF is reduced by NHg above 200"". TeFg, also a colourless gas, is hydrolysed by water ...
