Infrared and Raman spectra of L-citrullinium perchlorate crystals have been recorded at room temperature. The vibrational assignments of the observed wavenumbers are proposed on the basis of group theoretical analysis. The presence of carbonyl group indicates that the molecule exists in the ionic form. The shifting of stretching and bending wavenumbers indicates the presence of extensive hydrogen bonding in the crystal. The anion fundamentals however continue to be degenerated. This suggests that its symmetry is not affected in the crystal.
高氯酸L-瓜氨酸晶体的红外光谱和拉曼光谱已在室温下记录。基于群论分析对观察到的波数进行了振动归属。羰基的存在表明分子以离子形式存在。伸缩和弯曲波数的位移表明晶体中存在广泛的氢键。然而，阴离子的基频仍然简并。这表明其对称性在晶体中未受影响。
