(a) Dependence on temperature of the eccentricity of iso-intensity lines (in red) and of the two-dimensional RMS of the ODP functions (in blue) inferred from the eccentricity values. (b) Two-dimensional RMS width of the ODP as directly obtained from the intensity profiles at a fixed q value (see Fig. 4). Both plots show that a moderate decrease of the orientational order occurs as particles swell by taking in one more layer of water, at around 313 K. |
