Spectroscopic identification of molecular species of 12-tungstophosphoric acid in methanol/water solutions
(Elsevier Science Sa, Lausanne, 2012)
The various molecular species formed by decomposition of 12-tungstophosphoric acid (WPA) in methanol/water solutions of different composition, and over a pH range 1-12, were identified by UV, FTIR, micro Raman and P-31 NMR ...
