摘要：

In situ Raman spectra of D,L-mandelic acid were characterized under high pressure generated by diamond anvil cell at room temperature. The pressure was up to 2. 2 GPa. Around 0. 6 GPa, some original Raman peaks disappear or split, and some new Raman peaks emerge. Within the experimental pressure range, the curve of Raman frequence-pressure presented inflexions at 0. 6 GPa, indicating a phase transition from Pbca to P2(1)/c for D,L-mandelic acid has occurred at this pressure. On total release of pressure, the Raman spectra returns to its initial state, implying this transition is reversible.
