【摘要】：采用衰減全反射紅外光譜(ATR-FTIR)技術(shù),研究了固相葡萄糖的結(jié)構(gòu)。實驗發(fā)現(xiàn):固相葡萄糖同時存在著O-H伸縮振動模式(νOH),CH_2不對稱伸縮振動模式(νasCH_2),CH2對稱伸縮振動模式(νsCH2),CH2變角振動模式(δCH_2),C-O伸縮振動模式(νC-O),O-H面內(nèi)彎曲振動模式(δOH),葡萄糖環(huán)振動模式(νⅠ)和葡萄糖環(huán)呼吸振動模式(νⅢ)等。采用二維紅外光譜(2D-IR)技術(shù),研究了固相葡萄糖νⅠ和νⅢ。實驗發(fā)現(xiàn):固相葡萄糖存在著α-D-(+)-吡喃葡萄糖及β-D-(+)-吡喃葡萄糖兩種異構(gòu)體,并進一步來研究溫度變化對于固相葡萄糖異構(gòu)體結(jié)構(gòu)的影響。
[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，
