Multidimensional infrared spectroscopy is a robust tool for studying the structural dynamics of molecules. In particular, twodimensional infrared (2DIR) spectroscopy can reveal vibrational coupling among the internal modes of molecules, uncovering the transient structure of complex systems. While spectroscopically very powerful, current experimental techniques are time consuming to perform, requiring ~10(6) laser shots for a single 2DIR spectrum. In this work, we demonstrate a new technique that can acquire a full 2DIR correlation spectrum using a single ultrafast laser pulse. This apparatus will allow 2DIR spectroscopy to be extended to systems that were unattainable with previous technology, including, irreversible chemical reactions, rapid flow experiments, or with low repetition rate laser systems.
