| 摘 要： | 测量了在降温过程中体积比为1∶1的二甲基亚砜(DMSO)水溶液的拉曼光谱，并对DMSO水溶液的拉曼光谱进行了归属。对实验数据进行分析发现: 在降温过程中DMSO分子与水分子的分子间氢键、DMSO分子与DMSO分子和水分子与水分子间氢键的作用行为引起了DMSO的SO双键和水分子的O—H键的拉曼谱带的变化。进一步分析表明：在27～-30 ℃降温过程DMSO与水之间氢键加强，-30～-60 ℃降温过程水与水之间氢键代替DMSO与水之间的氢键。这为丰富水溶液的氢键理论提供了实验依据。 |

| Abstract: | In the present paper, DMSO/H2O mixture with the ratio of volume 1∶1 was measured in the cooling process by Raman spectroscopy, and the Raman assignments was made to the DMSO molecular and water molecular. The results showed that the behavior between intra-molecular hydrogen bonds and inter-molecular hydrogen bonds of DMSO and water leads to the change in the Raman spectra of the SO stretching vibration of DMSO and the O—H stretching vibration of water. Further analysis showed that the hydrogen bond between DMSO and water was enhanced in the course of temperature decreasing process (27 to -30 ℃), and the intramolecular hydrogen bonds between water and water replaced the intermolecular hydrogen bonds of DMSO and water in the course of temperature decreasing process (-30 to -60 ℃). The research provides experimental basis for hydrogen bonding theory in aqueous solution. |
