The first stable quantum gas of molecules with large electric dipole moments has been made by physicists in the US. Unlike other quantum gases, the molecules interact with each other over relatively ...

Polar diatomic molecules, consisting of potassium and rubidium, have been created with density and temperature close to the regime of quantum degeneracy. The ability to produce ultracold atoms has had ...

A News of the Week article claimed that all-cis hexafluorocyclohexane (HFC) with a dipole moment equal to 6.2 debyes is “the most polar nonionic compound now known to exist” (C&EN, March 30, page 5).
