Signatures of conical intersections in two-dimensional electronic spectra

摘要: Femtosecond two-dimensional (2D) electronic spectroscopy is a versatile technique for the exploration of ultrafast photoinduced dynamics in complex molecular systems. We have performed first computational simulation femtosecond 2D spectrum model system with conical intersection, using wave-function version equation-of-motion phase-matching approach. It shown that two-state two-mode intersection simultaneously provides information on complicated energy-level structure vibronically coupled states as well time-dependent population decay. The challenges and prospects future simulations spectra multi-mode intersections are briefly discussed.
