【摘要】：采用衰减全反射红外光谱(ATR-FTIR)技术,研究了固相葡萄糖的结构。实验发现:固相葡萄糖同时存在着O-H伸缩振动模式(νOH),CH_2不对称伸缩振动模式(νasCH_2),CH2对称伸缩振动模式(νsCH2),CH2变角振动模式(δCH_2),C-O伸缩振动模式(νC-O),O-H面内弯曲振动模式(δOH),葡萄糖环振动模式(νⅠ)和葡萄糖环呼吸振动模式(νⅢ)等。采用二维红外光谱(2D-IR)技术,研究了固相葡萄糖νⅠ和νⅢ。实验发现:固相葡萄糖存在着α-D-(+)-吡喃葡萄糖及β-D-(+)-吡喃葡萄糖两种异构体,并进一步来研究温度变化对于固相葡萄糖异构体结构的影响。
[Abstract]:The structure of glucose in solid phase was studied by attenuated total reflectance infrared spectroscopy (ATR-FTIR). It is found that there are O-H stretching vibration mode (OH), CH_2 asCH_2), CH2 symmetric stretching vibration mode (CH2 sCH2) and CH2 variable angle vibration mode (未 CH_2) in solid phase glucose. C-O stretching vibration mode (v C-O), O-H in-plane bending vibration mode (未 OH), glucose ring vibration mode), glucose ring breathing vibration mode (v 鈪，
