Femtosecond X-Ray Spectroscopy

Scientific Achievement

Molecular Foundry staff and users have, for the first time, directly characterized the 200 femtosecond electron movements of a chemical reaction’s transient state.

Significance and Impact

The reaction of cyclic molecules is a ubiquitous chemical process and a key step in the photobiological synthesis of vitamin D in the skin and in optoelectronic technologies underlying optical switching, optical data storage, and photochromic devices.
