Figure 3.

(a and b) Comparison of normalized intensity at the boson peak energy, as a function of Q for hGFP and dGFP at 295 K for the dry and hydrated states, respectively. The spectra are overlaid (dashed lines) for ∝Q², illustrating the expected spectra for random phase or out-of-phase collective motions. (Dotted line in panel a) Expected Q-dependence for a fully in-phase coherent motion, ∝S(Q)^∗Q². (c) Schematic of the fitting procedure used to decompose the random and coherent phase motions, shown here for the boson peak region of dry deuterated GFP at 295 K.
