✦ Synopsis

The angular distribution of photoelectrons ejected from the time-resolved resonant two-photon ionization of polyatomic molecules is theoretically studied taking into account the rotational k-coherence created by rotation-vibration (Coriolis) couplings in the resonant state. The structure of the angular distribution is clarified Model calculations are performed to see how the kcoherence due to a b-xis Coriolis coupling is reflected in the time-resolved angular distribution of photoelectrons.

Effects of vibronic dephasings on the time-dependent degree of polarization in the two-photon ionization of an isolated symmetric top molecule are theoretically studied. The so-called fast (picosecond) decays of polarization in isolated trans-stilbene are explained in terms of a Coriolis-induced vib
