Abstract
The dynamics of electronically excited states in 2-picoline is studied using femtosecond time-resolved photoelectron imaging spectroscopy. The internal conversion from the S2 state to the vibrationally excited S1 state is observed in real time. The secondarily populated high vibronic S1 state deactivates further to the S0 state. Photoelectron energy and angular distributions reveal the feature of ionization from the singlet 3p Rydberg states. In addition, variation of time-dependent anisotropy parameters indicates the rotational coherence of the molecule.Keywords
