Tracking ultrafast electronic changes in molecules is challenging, especially in liquids. An X-ray spectroscopy study in pyrazine now shows electronic dynamics created at conical intersections ...

At first glance, it might seem obvious that atoms touch each other, especially when you consider the material world around us ...

This interaction is determined largely by the electronic structure of atoms and molecules; photon absorption or emission is associated with an electron moving from one energy level to another.

Step into a world so tiny, it defies imagination -- the nanoscale. Picture a single strand of hair, now shrink it a million times. You've arrived. Here, atoms and molecules are the architects of ...

Led byJulian West, researchers developed a photocatalytic process that uses iron and sulfur catalysts activated by mild blue light to add chlorine atoms to organic molecules.

In the film, single molecules, consisting of two atoms bonded together, were magnified 100-million times and positioned frame-by-frame to tell a stop-motion story on an atomic scale. Achieving ...
