Figure 3
(a) S(Q, T) and corresponding normalized difference signals ΔS(Q, T₁)/ΔT for T₁ = 300–325 K and ΔT = 3 K, colour-coded according to T₁. The difference data are smoothed for clarity of presentation. (b) ΔT = 3 K difference signals for T₁ = 300 K and 325 K (grey circles, 325 K data offset) with a fit (black line) of the ESRF difference scattering signal $[\Delta S_{\rm{H_{2}O}}^{\,\rm{ESRF}}]$ , which is a linear combination of $[\Delta S_{\Delta T}^{\,\rm{ESRF}}]$ (red) and $[\Delta S_{\Delta\rho}^{\,\rm{ESRF}}]$ (blue) as defined in equation (1)
