Excitonic Coupling in Molecules

This lecture covers the temporal evolution of perturbed quantum systems, the interaction of molecules with light, electric transition dipole moments, selection rules for electronic transitions, exciton formation, Franck-Condon principle, absorption and emission spectra, Jablonski diagram, optical gap and degree of electronic delocalization, effective conjugation length, excitonic coupling in dimers, spectral signatures of H and J aggregates, Davydov splitting, spectroscopic aggregates, and learning outcomes related to the interaction of light with molecules.
