In 0.1 molL(-1) (pH 1.0) HCl medium, 12-tungstophosphoric acid (TP) reacted with malachite green (MG) to form an ion-association complex. As a result, the new spectra of RRS, SOS and FDS appeared and their intensities were enhanced greatly. The maximum wavelengths of RRS, SOS and FDS were located at 334 nm, 586 nm and 330 nm, and the scattering intensities(More)
In pH 1.0 HCl medium, 12-tungstophosphoric acid (TP) reacted with promethazine hydrochloride (PMZ) and chlorpromazine hydrochloride (CPZ) to form ion-association complexes, which led to a great enhancement of the resonance nonlinear scattering such as second-order scattering (SOS) and frequency doubling scattering (FDS). Their maximum SOS and FDS peaks were(More)
