Abstract: | ![]() It is argued that the infrared spectrum of L-lysine sulfate (L-Lys2+·SO4(2-)) published by Krishnakumar et al. [V. Krishnakumar, S. Manohar, R. Nagalakshmi, Spectrochim. Acta A75 (2010) 1394-1397] cannot belong to this crystal species. To confirm this, crystals (L-Lys2+·SO4(2-)) were synthesized and identified by XRD, and ATR FTIR and Raman spectra of L-Lys2+·SO4(2-) were registered and are discussed. |
