Now, the team has shown that the splitting of the IR peaks they observed is actually caused by the central fluorine atom in the F 5- tunnelling, spontaneously transforming the system between two ...

Chemists have yet another use for fluorine, as a through-space activator for electrophilic aromatic substitutions. Thomas Lectka and coworkers at Johns Hopkins University used a Diels-Alder ...

The halogen gas fluorine, on the other hand, is one electron short of a full outer shell—a perfect match for an atom such as cesium that has an electron to give.

American Chemical Society: Chemistry for Life.Hydrogen fluoride (HF) is an extremely toxic, corrosive gas and liquid. As the lightest of the hydrogen halides, it has a surprisingly high boiling point, ...
