Vibrational Coherence and Quantum Yield at the Conical Intersection of an Electron-Tunable Oxindole Photoswitch.
This talk explores how vibrational coherence influences quantum yield at conical intersections in electron-tunable oxindole photoswitches. Using ultrafast transient absorption spectroscopy, it examines how protonation changes photoisomerisation mechanisms and efficiency. The research connects molecular photophysics with biological photoreceptors, photopharmacology, optogenetics, molecular motors and light-driven energy technologies.
