Imaging the Temporal Evolution of Molecular Orbitals during Ultrafast Dissociation.

We investigate the temporal evolution of molecular frame angular distributions of Auger electrons emitted during ultrafast dissociation of HCl following a resonant single-photon excitation. The electron emission pattern changes its shape from that of a molecular s orbital to that of an atomic p state as the system evolves from a molecule into two separated atoms. [ABSTRACT FROM AUTHOR]
