Figure 5
Lifetime comparison of the water FCB eigenstates for: static self energy calculations (τ∑, j) (solid dots), exponential fits of the decaying population of a single initially populated level (τs, j) (green curves), exponential fits of the total population of all excited states, starting from a single initial populated FCB level (τa, j) (red curves). Dotted curves correspond to elastic ECEID real-time calculations, dashed and solid lines to N(0) = 0 and N(0) = 2 ECEID simulations, both with 
kept equal to 0.
