摘　　要：采用漫反射红外光谱技术研究葡萄糖的结构。结果发现:葡萄糖同时存在着O—H伸缩振动模式(ν_(OH))、CH_2不对称伸缩振动模式(ν_(asCH_2))、CH_2对称伸缩振动模式(ν_(sCH_2))、C=O伸缩振动模式(ν_(C=O))、C—O伸缩振动模式(ν_(C—O))、O—H面内弯曲振动模式(δ_(OH))等。采用漫反射二维红外光谱技术研究了葡萄糖ν_(C=O)。实验发现,葡萄糖存在着缔合态直链葡萄糖及游离态直链葡萄糖,室温下缔合态直链葡萄糖分子结构稳定。Diffuse reflection infrared spectroscopy was used to study the structure of glucose. The results of study have shown that O-H expansion and contraction vibration mode （Vo.）, CH2 asymmetrical expansion and contraction vibration mode （VascH2 ）, CH2 symmetrical expansion and contraction vibration mode （Vscn2）, C=O expansion and contraction vibration mode （Vc=o ）, C-O expansion and contraction vibration mode （νC=O ） and O-H in-plane bending vibration mode （δOH） , etc. coexist in glucose. Diffuse reflection infrared spectroscopy was used to study νC=O of glucose, The results of experiment have shown that glucose exists in the form of associated straight chain glucose and in the form of free straight chain glucose. The effect of room temperature on the change of the molecular structure of straight chain glucose was further studied. Key words glucose; diffuse reflection; two-dimensional infra-red spectra; molecular structure; vibration mode
