The Photochemistry of Rydberg-Excited Cyclobutanone: Photoinduced Processes and Ground State Dynamics

Owing to ring-strain, cyclic ketones exhibit complex excited-state dynamics with multiple competing photochemical channels active on the ultrafast timescale. While the excitedstate dynamics of cyclobutanone after π ∗ ← n excitation into the lowest-energy excited singlet state (S1) has been extensively studied, the dynamics following 3s ← n excitation into the higher-lying singlet Rydberg (S2) state are less well understood…
