Two-dimensional electronic spectroscopy (2DES) is a method well suited to studying the ultrafast dynamics and electronic structure of molecular aggregates. In 2DES, the initial absorption frequencies of the system are correlated with the emission frequencies as a function of time between excitation and detection. The resulting 2DES spectra contain rich information about electronic structure and dynamics. Coherent and fluorescence-detected 2DES are complementary experiments that yield dramatically different spectra due to the different combinations of signal contributions produced in the two experiments. I am working on implementing fluorescence-detection to the existing coherent 2DES set-up in the Ogilvie group to explore the benefits of measuring both coherent and fluorescence-detected 2DES spectra for extracting electronic structure and dynamics of molecular systems and larger molecular aggregates such as photosynthetic systems.
