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。
The solid phase glucose structure had been studied by fourier transform attenuated total reflection infrared spectroscopy (ATR-FTIR). The O-- H stretch vibration (VOH), C Hz a- symmetrical stretching vibration (vasCH2), CH2 symmetrical stretching vibration ( vsCH2 ), CH2 scissoring vibration(δCH2), C-- O stretch vibration(vc-o), O-- H in-plane bending vibration (8OH), glucose skeleton vibration mode (vi) and glucose skeleton breathing vibration (Ⅲ) were found. The solid phase glucoses and vm had been discussed by two-dimensional infra- red spectroscopy(2D-IR). The α-D-glucopyranose and β-D-glucopyranose were discoverd and influence of temperature change on solid glucose structure was researched by 2D-IR also.
