B2(TO) and B2(LO) Raman spectra of LiNH4C4H4O6·H2O crystals have been separately obtained in the temperature range between 77 K and room temperature. Anomalous low-lying response was observed in both B2(TO) and B2(LO) spectra, and its intensity was found to decrease gradually with decreasing temperature and vanish below Tc(=98 K). It is concluded that the low-lying response is not attributed to the NH4 group.
