(Top) LAXS radial distribution curves for a 1.833 mol·dm−3 aqueous solution of dioxovanadium(IV) sulfate, L4a. Upper part: Separate model contributions (offset: 18) of the hydrated dioxovanadium(V) ion (green line), the sulfate ion (purple line), aqueous bulk structure (yellow line) and V···S distances (magenta line). (Middle) Experimental RDF: D(r)−4πr2ρo (red line); sum of model contributions (black line); difference (blue line).
(Bottom) Reduced LAXS intensity functions s·i(s) (black line); model s·icalc(s) (red line).
