Abstract
Brillouin spectra of partially deuterated triglycine selenate (similar to 5 0%deuteration) have been taken in the vicinity of the transition temperatur e 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 charac ter reported from earlier dielectric constant and hysteresis loops measurem ents.
