<h3><span style="font-size: 12.16px;">Transient Raman Spectroscopy for Probing Charge Transfer States</span></h3>
<p><strong><span style="font-size: 12.16px;"><span style="text-decoration: underline;">Abstract</span> :</span></strong></p>
<p><span style="font-size: 12.16px;">Charge transfer (CT) states form the basis for multitude of chemical reactions, and has become relevant due to its ubiquity in all light energy conversion paradigms.[1] In order to discover new materials with optimized charge transfer rates at molecular interfaces for energy conversion technologies, it is imperative to diagnose the structure-function corrleations “in operando”. Tracking the non-equilibrium nuclear dynamics leading up to the charge transfer states and probing the subsequent separation of charges requires time-resolved spectroscopy with structural sensitivity. In this talk, I will discuss the utility of transient Raman spectroscopy as a tool to structurally probe the formation of CT states in molecular dyes with large Stokes shift,[2] and uncover the hidden lengthscale of the photochemistry inside the active site of metalloproteins.[3] Both frequency domain and time-domain methods will be elaborated with emphasis on challenges of real-time Raman detection during chemical reactions.</span></p>
