采用变温装置,在-30℃至-190℃温度范围内我们对冰行进了原位低温拉曼光谱测量.并利用光谱分析软件对冰的拉曼光谱带行进了分析,得到O-H键振动的三个拉曼峰随温度的变化规律.应用氢键理论对实验结果进行了分析,结果表明O-H键的比(最)反对称伸缩振动和v1(B1g)不同向对称伸缩振动受氢键影响较大,并且V3(Eg)的拉曼峰位与温度成很好的线性关系有潜在的应用价值.
Using variable temperature equipment, we measured the Raman spectra of the ice at temperatures ran- ging from -30℃ to -190℃. We also used computer software to resolve peaks, and show that the temperature de- pendences of the three Raman peaks of the OH bond vihratiorL Based on the experimental results and analysis with hydrogen bond theory, the results showed that the asymmetrical streching vibration v3 (Eg) and the syrmnetrical streching vibration v1 (B1g) Of the O-H bond were great affected by hydrogen bond, and the linear relation of the Raman shift of v3 (Eg) was excellent with temperature.
