Photoemission and coincidence studies of molecular dynamics using synchrotron radiation

Research output: Contribution to journalArticlepeer-review


Two typical cases, ultrafast dissociation of the SF6 molecule following F 1s excitation and complete atomization of the BF3 molecule following F 1s core-hole creation and are described. High resolution resonant Auger electron spectroscopy is used for SF6, whereas a multiple-ion coincidence momentum imaging is applied to BF3. It is shown that both measurements allow a direct characterization of the asymmetric nuclear motion which follows the electronic excitation.
