      Two-dimensional electronic spectroscopy (2D-ES) with ultrashort pulses is a state-of-the-art tool for the investigation of molecular dynamics, line broadening mechanisms and molecular coherence phenomena. The standard technique for studying molecular processes after electronic excitation is pump-probe. In this talk, I will show that 2D-ES yields valuable information unattainable with other techniques. I will discuss several experimental studies where 2D-ES lead to insightful and experimentally well-founded perspectives on intricate molecular photodynamics. Examples are the excition dynamics in a tubular aggregate, the deactivation network in carotenoids and the relaxation pathways in an artificial light harvesting system. In an outlook, I will demonstrate how 2D-ES is easily implemented and upgraded by the use of pulse shaping devices.
