Abstract

The information contained in time-resolved PEI experiments was studied. A nonperturbative quantum mechanical theory was applied to compute the time-resolved differential cross section for a polyatomic molecule. Focus was on the case of an ultrafast radiationless transition. It was shown that the energy-resolved ionization asymmetry parameters, derived from PEI, serve to map the electronic population dynamics, effectively filtering out the vibrational dynamics with which the electronic modes are strongly coupled.
