In a weak acid medium, when an isopoly-tungstic acid reacts with berberine to form an ion-association complex, strong resonance Rayleigh scattering (RRS) appears and obvious frequency-doubling scattering (FDS) as well as second-order scattering (SOS) come into being. The scattering peaks

This study is focused on the composition and the evolution of tungstate ions solutions as a function of pH and increasing concentrations. The Raman analysis showed that, during the titration of the tungstate solutions, WO4(2-), HWO4- ions and probably W2O7(2-)
