为了进行水质分析,运用激光拉曼光谱方法测量了自来水和白开水的拉曼光谱,分析了其振动方式归属与光谱强度。结果表明,3200～3400cm-1较强的拉曼谱带(伸缩振动)是水分子的振动拉曼特征峰,水中杂质尤其是钙镁离子含量是影响拉曼特征峰强度的主要因素。 For water quality analysis, the Raman spectra of tap water and boiled water were measured by laser Raman spectroscopy. The vibration modes and spectral intensity were analyzed. The results show that the Raman band (stretching vibration) of 3200 ~ 3400cm-1 is the vibrational Raman peak of water molecules. The impurities in water, especially the content of calcium and magnesium ions, are the main factors affecting Raman peak intensity.
