Overview of project A06
Non-Equilibrium Charge Transfer between Solids and Adsorbates in Vacuum and at Electrified Solid / Liquid Interfaces
In electrochemistry charge transfer between solid and electrolyte is fundamental. While prior studies clearly show that all aspects of the interface influence electron transfer rates, experimental insight into mechanism has been limited. In project A06 we address this problem by initiating electron transfer with a short laser pulse and tracking the correlated structural changes, principally using several types of surface sensitive vibrational spectroscopy. That allows us to track the temporal evolution as the electron moves between solid and electrolyte. In particular we will elucidate the role of non-bonded interactions in controlling chemistry using 2D vibrational techniques.
