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 S ₁ 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.
