Abstract:
Ultrafast intramolecular electronic charge separation during photo-chemical reactions cause up to tenthousand surrounding molecules to perform aligning pirouettes. Researchers observed for the first time such light induced reorientations in an organic molecular crystal. Scientists of the Max-Born-Institute for Nonlinear Optics and Ultrafast Spectroscopy and of the Ludwig-Maximilians-University in Munich report their recent experimental results in the current issue of the journal Physical Review Letters (" Ultrafast Changes of Molecular Crystal Structure Induced by Dipole Solvation").
