Abstract
Internal vibration modes of(n-(C3HNH3)-N-7)(2)SbBr5 and (n-C3H7NH3)(3) Sb2Cl9 were studied through their phase transitions using the infrared spectroscopy. The studies show that the vibrational states of the n-p ropylammonium cati6nS change considerably during the phase transitions . The V(CC), V(CN) and V-s(NH) bands are very sensitive to the phase t ransition at 154 K in (n-C3H7NH3)(2)SbBr5, and at 232 K in (n-C3H7NH3) (3)Sb2Cl9. IR spectra point out the key role of the n-propylammonium c ations in the phase transition mechanism of both crystals.
