網頁The stereochemical activity of lone pair electrons has been shown to cause distortions of Jahn–Teller geometry [5,6], a large optical response in TeO2-based … 網頁In VSEPR theory, these stereochemically inactive lone pairs are rationalised by placing them in an s-orbital, which is non-directional. An electron pair in an s-orbital has a spherically symmetric electron density, and hence cannot influence the shape of a molecule.
