In addition, for Ama + , the D 1 population is initially rather large (∼0.3) and the D 0 -D 1 energy gap steeply decreases within the first 12 fs -this should facilitate D 1 → D 0 transitions in Ama + . Overall, the recovery of the ground state occurs faster for Ama + than for Ada-CN + , considering the same energy window of eV.
