摘要：

Brillouin spectra of partially deuterated triglycine selenate (similar to 50%deuteration) have been taken in the vicinity of the transition temperature for longitudinal phonon configurations q \ [101] and q \ [011], Very weak anomalies were observed at T(C)congruent to 27 degrees C, and the spectra did not show up any feature indicative of the first order transition character reported from earlier dielectric constant and hysteresis loops measurements.
