摘要：

Single-crystal samples of monohydrated I-asparagine, C4N2O3H8. H2O, a fundamental aminoacid of the human body and other complex beings, have been studied by Raman spectroscopy in a diamond-anvil cell up to pressures of 2.0 GPa. From the analysis of results we observed that the crystal undergoes a series of three phase transitions. All transitions are accompanied by drastic changes in the external modes and in some internal modes of the crystal, which shows in a clearway the transitions induced by the hydrostatic pressure. Pressure coefficients for external modes are also given. (C) 1997 Elsevier Science Ltd.
