Description of the solution scattering experiment. (a) Schematic of the liquid unit cell V of sample A. The gray surface shows the van der Waals volume of the solute, defining the excluded volume. (b) Schematic of an equivalent volume V of sample B, showing how the excluded volume defines a droplet of solvent atoms (shown in blue). For clarity, only a half of the solvent atoms outside the excluded volumes are rendered. |
