Tag: Raman scattering

Researchers have observed the production of electronic excitations near a single atom in a molecule. This is caused by impulsive stimulated X-ray Raman scattering of X-ray pulses that last less than a femtosecond. The combination of X-ray Raman scattering and the ability produce sub-femtosecond X-ray pulses allows scientists to view motion in molecules at atom-scale resolution and helps them understand chemical reactions involving light.
