摘要

收起

利用金刚石对顶砧（DAC）装置产生高压，在室温下对环庚烷进行了高压原位拉曼光谱研究。实验的最高压力是17.00 GPa。研究结果表明，在实验的压力范围内，室温常压下为液态的环庚烷在0.53 GPa发生了液-固相变；在3.45~5.58 GPa压力区间，环庚烷的拉曼频移随压力变化的曲线和拉曼峰的半高宽随压力的变化曲线都出现了拐点，由此判断，环庚烷可能发生了固-固相变。

关键词

Abstract

收起

In situ Raman spectra of cycloheptane have been characterized under high pressure generated by diamond anvil cell (DAC) at room temperature. The pressure is up to 17.00 GPa. With the increase of pressure, the cycloheptane experienced the liquid-solid phase transition at 0.53 GPa. During 3.45~5.58 GPa, both the curve of Raman frequence-pressure and FWHM-pressure presented inflexions, indicating a potential solid-solid phase transition of cycloheptane.

Key words

cycloheptane / Raman spectra / high-pressure / phase transition / diamond anvil cell (DAC)
