摘要：
Raman and infrared spectra (20-5000 cm-1) of (CH3)2NH2ClO4 and its N-deuterated analogue were investigated in the temperature range 90-350 K. A temperature dependent study of widths and frequencies of prominent bands confirms (a) the existence of phase transitions at 309 and 311 K and (b) in the high temperature phases II and I, the cations and anions undergo reorientational motions.
