Electronic Perturbations: Vibronic Coupling and Light-Matter Interaction

This lecture covers the concepts of vibronic coupling and light-matter interaction in organic electronics. It starts with a discussion on intramolecular electron delocalization and then delves into the intrinsic and extrinsic electronic perturbations, focusing on vibronic coupling and light-matter interaction. The lecture also explores charge formation, delocalization, and transport in organic materials, along with the preparation of organic semiconductor materials. Advanced topics such as defects, sensors, bioelectronics, and sustainable electronics are also discussed. The interaction of molecules with light, quantum systems perturbed by periodic perturbations, and selection rules for electronic transitions are explained. The lecture concludes with exciton formation, Franck-Condon principle, and spectral signatures of H and J aggregates.
