| Research Abstract |
Ultrafast coherent Raman spectroscopy was utilized to track global motions of nuclei across the framework of stilbene molecule during its photoinduced cis-trans isomerization. Observing the gradual frequency shift of a skeletal vibration and its theoretical calculation provided a thorough picture of how each atom in the molecule rearranges associatedly and continuously toward the twisted configuration.
