以合成包裹体作压腔进行高温下NaCl-CO_2-H_2O混合流体的拉曼光谱原位分析

An in-situ Raman Spectroscopy Study of NaCl-CO_2-H_2O Fluids at High Temperatures Using Synthetic Inclusions

用合成包裹体作为压腔 ,用显微激光拉曼探针原位分析了温度达 5 5 0℃的 Na Cl- CO2 - H2 O体系的流体中水的结构。由流体中水的伸缩振动峰的变化可以揭示氢键作用随温度和相态变化。

The structure of water in the NaCl-CO 2-H 2O system at temperatures up to 550℃ in synthetic inclusions was studied by Raman spectroscopy.The changes of peak width and position of stretching vibration of water molecule give information on the variation of hydrogen bonding with the temperatures and the phase behavior.
