(Developing a thorough mechanistic understanding of photoexcited charge transfer and proton transfer reactions at the molecular-level requires a deep knowledge of coupled electronic and nuclear motion. Two-Dimensional Electronic-Vibrational (2D EV) spectroscopy and Two-Dimensional Vibrational-Electronic (2D VE) spectroscopy are recently developed techniques that are directly sensitive to molecular vibronic couplings. This dissertation advances 2D EV spectroscopy by implementing new broadband femtosecond light sources in the UV (370 nm - 440 nm) and the mid-IR (1600 cm-1-3200 cm⁻¹) frequency domains) p. 28 (2D Electronic-Vibrational (EV) spectroscopy; third order nonlinear spectroscopies employ electronically- and vibrationally-resonant excitation and probe fields to directly interrogate inter- and intramolecular vibronic couplings in molecular systems) p. 137 (multidimensional spectroscopic applications using pulse shapers, such as the 2D EV experiments described in this dissertation)
