Researchers have observed a molecule in the first instants after it has absorbed light and tracked the coordinated motion of electrons and nuclei with a temporal resolution of three femtoseconds. This is the result achieved by an international research group led by the Politecnico di Milano, which has developed a new apparatus for studying ultrafast photochemical processes.
