Abstract

(Figure Presented) The ultrafast S2 → S1 internal conversion of pyrazine through a conical intersection of the potential energy surfaces was clearly observed by ultrafast photoelectron imaging. The 2D time-energy map of the photoelectron angular anisotropy revealed a clear signature of the internal conversion (the color change of green-orange-green in the horizontal direction) at ∼0.9 eV. The orange color at ∼20 fs and 0.9 eV was found to correspond to the non-Koopmans ionization process from S 2(π,π*) to D0(n-1).
