摘要
采用中红外(MIR)光谱技术,包括一维MIR光谱、二阶导数MIR光谱、四阶导数MIR光谱和去卷积MIR光谱分别开展六氟异丙醇分子结构的研究。试验发现,六氟异丙醇分子的主要红外吸收官能团包括ν_(asCF3-六氟异丙醇)、ν_(sCF3-六氟异丙醇)、ν_(CO-六氟异丙醇)和δ_(asCF3-六氟异丙醇)等。采用一维MIR光谱开展了六氟异丙醇-水溶液结构的研究,研究发现,随着六氟异丙醇浓度降低,六氟异丙醇-水溶液分子间的氢键作用逐步减弱。并进一步进行了相关机理研究,为六氟异丙醇-水溶液的结构研究建立了一个新的方法学,具有重要的应用研究价值。
The molecule structure of hexafluoroisopropanol had been studied by middle infrared(MIR) spectroscopy(including one-dimensional MIR spectroscopy, second derivative MIR spectroscopy, fourth derivative MIR spectroscopy and deconvolution MIR spectroscopy). The infrared absorption mode of hexafluoroisopropanol molecule included ν_(asCF3-hexafluoroisopropanol), ν_(sCF3-hexafluoroisopropanol), ν_(CO-hexafluoroisopropanol) and δ_(asCF3-hexafluoroisopropanol). The structure of hexafluoroisopropanol-water solution were researched by one-dimensional MIR spectroscopy. With the decrease of hexafluoropropanol concentration, the hydrogen bonding between molecules were further weakened and the mechanism were also studied. In this paper, a new methodology was established for the study of hexafluoroisopropanol-water structure, which had important value of applied research.
