We demonstrate that driving bridge-localized vibrations in transition metal Donor-Bridge-Acceptor systems using a narrow-band Infrared laser pulse can influence the rates of electron transfer non-uniformly across different electronic states. We use a 3-pulse laser setup to electronically excite, vibrationally perturb and probe the charge transfer dynamics and pathways. These results provide further evidence of the importance of bridge-localized vibrational modes in mediating charge transfer, suggesting the possibility of controlling electron transfer rates and pathways in molecular systems using low-energy pulses.
