Raman spectroscopic studies of the structure of supersaturated ammonium dihydrogen phosphate solutions

• Raman spectroscopic studies of quiescent under and supersaturated ammonium dihydrogen phosphate (ADP) aqueous solutions were performed on the nu //1 (totally symmetric or breathing mode) and nu //3 (symmetric twist) H//2PO//4 OVER BAR bands as well as for the nu //1 band of solid ADP and solid diammonium hydrogen phosphate (DHP). The splitting of the non-degenerate ADP nu //1 band in concentrated solution is interpreted in terms of a well-ordered quasi-crystalline solution structure. Increases in nu //1 half-width at half-height support this view.
