## Abstract Infrared and Raman spectra (5–3500 cm^βˆ’1^) of polycrystalline samples of (C~3~H~7~NH~3~)~2~PbCl~4~ and of its deuterated derivative were investigated in the temperature range 90–300 K. An assignment of the observed bands at room temperature is proposed. A temperature dependence study of
