Abstract

Raman spectroscopic studies of NaNO3 solutions were performed to study solute clustering in supersaturated solutions. The results suggest that solute clustering occurs in undersaturated, saturated, as well as supersaturated solutions. the solute clusters do not resemble a crystalline-phase structure, rather they are solvated clusters consisting of solute and solvent molecules. There are some indications that as the solution becomes supersaturated, some of the solute clusters coalesce into larger clusters at the expense of other clusters and the dilution of lower-ordered species. Current results suggest that the mechanisms governing the crystallization from solution are associated with the coalescence of solvated solute clusters and/or changes in their properties and structures.
