Two-dimensional Vibrational-Electronic (2D-VE) spectroscopy provides direct access to the couplings and correlations between vibrational and electronic transitions. We present a Fourier transform 2D-VE setup that employs compressed broadband white-light probing to resolve changes in electronic spectra induced by infrared (IR) excitation. These changes arise from vibronic couplings that are mode- and molecule-specific and can, for example, be used to disentangle congested spectra. As a demonstrat
