Acceptor population vs. $t_1$ at $t_2=3$ fs (right after the X-ray pulse) in the Ru–Co model complex. (A) Population without the X-ray pulse $P_A^{\left(0\right)}\left(t_1\right)$. (B) Incremental population due to X-ray $\mathrm{\Delta }{P}_A$ for different phases ϕ; (C) for different amplitude ratio η and $\varphi =0$; (D) Same as in C but for $\varphi =\pi$.
