Line Plot from Scientific Research

The r.m.s. value of ΔG(r) calculated over equally sized ranges of interatomic distance, showing the same initial prompt response at 0 ps but a difference in further structural evolution at local and non-local length scales. ΔG(r) r.m.s. value over the 34–41 Å range follows an exponential behaviour with (38 6) ps characteristic time (black dashed line). The r.m.s. value of ΔF(Q) is also shown (grey), representing all the accessible length scales. ΔF(Q) normalized to match negative delay values for ΔG(r) (representing the noise level). The error bars indicate uncertainty only due to photon shot noise.
