Femtosecond Nonadiabatic Confinement of Molecular Dication Yield
Carlos Marante, Lina Fransén, Alexie Boyer +5
Doubly charged molecular cations often carry signatures of electronic correlation and electron-nuclear entanglement present in the parent cation. Here, we produce ethylene dication…

Attochemical control of nuclear motion despite fast electronic decoherence
Lina Fransén, Sandra Gomez, Morgane Vacher
Short-in-time, broad-in-energy attosecond or few-femtosecond pulses can excite coherent superpositions of several electronic states in molecules. This results in ultrafast charge o…

Tracking photophysical relaxation in spiropyran with simulated time-resolved X-ray absorption spectroscopy
Lina Fransén, Benjamin Roux, Sonia Coriani +2
Spiropyran is a prototype photoswitch that undergoes photoinduced ring-opening via C-O bond fission. The quantum yield for this photochemical reaction is low, with photophysical re…
