Figure 4.

(top)Time variation of the normalized natural orbital SVD weights $w_{\xi }^2(\tau )$ for each particle-hole pair ξ with wavepackets created by pulses at τ = 0 followed by a second pulse at τ = 24.2 fs (dashed line). Each of these pulses can be tuned to be resonant with either the N,O or S K-edges, giving rise to the nine scenarios, as indicated.
