Characterization of solution structure near the surface of a growing crystal by Raman spectroscopy

• In situ structure analyses of the supersaturated aqueous NaNO//3 solution near a growing NaNO//3 crystal have been performed using micro Raman spectroscopy. It was observed that the relative concentrations of higher ordered species (contact-ion pairs, and ion aggregates) are diminished near the growing crystal, indicating that these species are dominant in the diffusion process when compared to free aquated ions or solvent-separated ions. There were no detectable differences between the spectra obtained for saturated and supersaturated solutions.
