摘要：

Results of a low-temperature Raman and ultrasonic investigation of triglycine sulphate (TGS) and its deuterated isomorph (DTGS) are presented. The existence of low-temperature phase transitions at 110 K and 130 K in TGS and DTGS respectively is considered. A large isotopic shift indicates that the transitions involve ordering of the NH3 (ND3) groups.
