The cover picture shows an artist's view of the dynamical evolution of the bimetallic cluster Ag 2 Au in the neutral electronic ground state after photodetachment of the anion. Femtosecond negative ion–to‐neutral–to‐positive ion (NeNePo) pump‐probe spectroscopy (open circles) at two different probe wavelengths (blue: 350 nm; red: 406 nm) and theoretical simulations (solid lines) are employed to monitor the dynamical processes of geometry relaxation followed by intramolecular vibrational energy redistribution (IVR) to the probe‐wavelength dependent NeNePo signals. In their Article on page 243 Bernhardt et al. provide detailed insight into the ultrafast nuclear dynamics in this model‐type cluster system.
