Abstract

Using an ultrafast electronic-vibrational pulse-sequence, we show that the outcome of light-induced ET can be radically altered by mode-specific infrared (IR) excitation of vibrations which are coupled to the ET-pathway. IR-control is particularly challenging in condensed phase systems due to the ultrafast timescales involved, in particular rapid intramolecular vibrational redistribution. We demonstrate how an IR-pulse following UV-excitation perturbs nuclear-electronic (vibronic) interactions within a donor-bridge-acceptor system similar in design to those utilized in (bio)chemical light-harvesting, and alters charge-transport pathways and product state yields.
