<h3>Reaction Mechanisms</h3><p>Coherent motions in form of specific delocalized nuclear motions usually arising from low-frequency modes have been frequently suspected to play a key role in photoactive systems. Consequently, tracing transient changes in atomic positions and elucidating reactive nuclear coordinates within a polyatomic system becomes imperative. Using combination of steady-state electronic spectroscopy along with pump-probe electronic and time-resolved Raman spectroscopy, our group aims to develop a unified mechanism of photoactive systems driven by collective motions in many of the potent artificial and natural molecular systems. In addition, we are also working towards unravelling the role of protein motions in chemically triggered enzyme action.</p><h3>Molecular Materials</h3><p>In the quest for renewable energy, developing an inexpensive light harvesting technology will be incumbent upon us within the next few decades as we move away from the finite natural resources. In this context, designing new materials for photocatalytic processes with high photochemical efficiencies is crucial. One of the key features in all new materials will be its robustness during the entire catalytic cycle. We are exploring ways in which we can stabilize reactive intermediates inside environments conducive to multi-electron reactions.</p>
