The vibrational density of states power spectrum (black) and kinetic energy distribution (red) for water molecules A and B, W_A (panel A) and W_B (panel B), on the ASW surface at several delay times after the formation of CO₂ using the MMH-PES. Panel C reports the vDOS and kinetic energy distribution for CO₂. Top panel: Averaged vDOS spectrum and kinetic energy distribution from 10 randomly chosen surface water molecules from data before recombination takes place. Subsequent panels are labeled with the time interval after CO₂ recombination.
