Femtosekunden-Photoelektronenspektroskopie an isolierten Multianionen

The ultrafast excited state dynamics and electronic structure of molecular multianions are studied via femtosecond time-resolved photoelectron spectroscopy in gas phase. Investigations on isolated molecules give direct access to intrinsic photophysical properties fading out any disturbing influences of the local environment - with remarkable effects for multiply charged species. Excited state electron tunneling detachment is highlighted as a unique pathway in the photophysics of multianions.
