Tsukuba, Japan—The shapes of simple polyatomic molecules such as carbon dioxide and methane are characterized by a specific symmetry depending on the manner of linking of the atoms. Nano- to ...

Researchers describe using a novel method combining cryogenic technology and direct laser light to cool the nonlinear polyatomic molecule calcium monomethoxide (CaOCH3) to just above absolute zero.

A far more accurate method for calculating the energies with which positrons — the antimatter equivalent of electrons — bind to molecules will enhance techniques that use them to probe materials.
