Spectroscopy is a very valuable tool for exploring the nature of matter in physical and chemical research. The interaction between light and matter makes it possible to observe the energy level and dynamics of the observation system. Two-dimensional electron spectroscopy allows people to understand the dynamics of complex molecular systems by analyzing correlation graphs. It is an ultrafast nonlinear spectroscopy method with high time and spectral resolution. This review first explains how two-dimensional electron spectroscopy broke through the double limitation of Heisenberg's uncertainty principle and wave packet collapse, making it theoretically possible. Then introduced the experimental design and specific device to realize the two-dimensional electronic spectroscopy method, and strived to clarify the principle and use method of the instrument. Finally, the application of two-dimensional electronic spectroscopy and the future prospects are introduced, and it is expected that this method can be popularized and used in other fields.
