This week’s Image of the Week shows the highest occupied molecular orbital (HOMO) wavefunctions of a sulphur hexafluoride (SF6) molecule. SF6 is a useful molecule because of its non-flammable, non-toxic and inert qualities. It is used widely in industry in lasers, plasma etching and and as an electrical insulator. However, it is also a greenhouse gas with high global warming potential, so knowledge of its properties is very important.
In their paper Sulphur hexaflouride: low energy (e,2e) experiments and molecular three-body distorted wave theory, Kate L Nixon et al 2 obtain triple differential ionisation cross-sections for the highest occupied molecular orbital of SF6 both experimentally and theoretically and compare their results.
