水和重水的拉曼光谱研究

Near IR FT-Raman Spectroscopic Measurement of Distilled Water and Heavy Water

本文对水和重水进行了近红外ＦＴ－Ｒａｍａｎ光谱测试。探讨了随着激发功率的增加，水和重水内部分子结构变化的规律，并运用去卷积技术对所得到的光谱进行了分峰处理，看出水分子的氢键有断裂趋势，并给出了一些定性解释，为今后进一步开展水溶液体系的近红外ＦＴ－Ｒａｍａｎ光谱的研究工作打下了一定基础。

The NIR FT-Raman spectra of H_2O and D_2O have been studied in this paper. The result shows that the hydrogen bonds of water molecules can be broken with the laser power increased．It also can be seen that the structure of the H_2O and D_2O molecules is changed．These spectra were treated by means of the deconvolution technique．The experimental result has discussed tentatively.
