摘要
开展了乙二醇羟基伸缩振动模式(ν_(OH))二维红外光谱的研究,探索了温度变化对于乙二醇氢键作用的影响。实验结果表明,随着测定温度的升高,游离乙二醇并不稳定,这是由于氢键作用进一步生成缔合态的乙二醇。本项研究拓展了二维红外光谱技术在氢键作用方面的研究范围。
The ethylene glycol hydroxy expansion and contraction vibration mode （VoH） was studied, and the effect of temperature change on the hydrogen bonding of ethylene glycol was discussed. The results of experiment have shown that the free ethylene glycol is not stable as the rise of measuring temperature because that associated ethylene glycol is further produced due to hydrogen bonding. This study has extended the scope of two-dimensional infrared spectroscopy study on hydrogen bonding.
