研究了L-精氨酸盐酸盐一水合物单晶在295 ~ 10 K温度范围内的偏振拉曼光谱。讨论了几个谱带的线宽、波数和强度的行为，并将其与氢键相关的某些特定振动模式或甚至与其他振动，如CN、CCC、CCN和CH振动联系起来。晶格振动区某些带的消失与晶体在100 ~ 110 K之间发生的相变有关。版权所有（C）2002约翰威利父子有限公司
Polarized Raman spectra of L-arginine hydrochloride monohydrate single crystal were studied at temperatures ranging from 295 to 10 K. The behavior of the linewidth, wavenumber and intensity of several bands is discussed and related to some particular vibrational modes associated with hydrogen bonds or even to other vibrations, such as CN, CCC, CCN and CH vibrations. The disappearance of some bands in the lattice vibrational region was associated with a phase transition undergone by the crystal between 100 and 110 K. Copyright (C) 2002 John Wiley Sons, Ltd.
