Program Understanding nuclear and electronic dynamics of molecular systems has advanced considerably by probing their nonlinear response with suitable sequences of shaped pulses. The ability to control various features of the excitation pulses such as duration, sequence, frequency, polarization, and shapes has led to a variety of time-resolved spectroscopic methods. Among them, two dimensional electronic spectroscopy (2D-ES) with ultrashort pulses is becoming a more and more popular tool because it allows us accessing the third-order susceptibility of the investigated sample and getting information on molecular dynamics, line broadening mechanisms and quantum coherence phenomena in biology and molecular complexes in general. In our group it has been implemented a 2D ES set-up, which exploits the versatility of pulse-shaping methods to achieve a full control on the amplitude and phase of the exciting and probing pulses. In this talk, I will explain first the basics of 2D-ES also in comparison to other ultrafast experimental techniques like pump-probe. Then, with a special focusing on biological systems, I will discuss several experimental studies where 2D-ES lead to insightful and experimentally well-founded perspectives on intricate molecular population- and coherence-dynamics. From this discussion I will show the unique advantages that originate from using shaped pulses and several possible detection schemes where we take advantage of phase and amplitude modulations.
