| 摘 要： | 用激光拉曼光谱对几种常见盐水溶液进行测定 ,并采用了两种不同的方法对数据进行分析 ,结果表明强度比值法对Na2 CO3、NaHCO3、Na2 SO4 等具有强拉曼特征峰的盐水溶液适用 ,而频移参数法对NaCl溶液效果较好。同时观察到 ,当水溶液中盐度越大时 ,水拉曼峰的不对称性越明显。

| Abstract: | We have used Laser Raman spectroscopy to experiment on salt water, and introduced two different constants-intensity ratio and skewing parameter, to analyze experiment data. The results show that the intensity ratio is suitable to salt water with Na 2CO 3?NaHCO 3?Na 2SO 4 which have strong Raman information, however, the skewing parameter can describe NaCl liquid better. In the same time, experiment results imply that the asymmetry is more remarkable when salinity is bigger. |
