✦ Synopsis

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 vibronic dephasing mechanism.

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 angu
