【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）,CH₂不对称伸缩振动模式（νasCH₂）,CH2对称伸缩振动模式（νsCH2）,CH2变角振动模式（δCH₂）,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。更多还原

【Abstract】 The solid phase glucose structure had been studied by fourier transform attenuated total reflection infrared spectroscopy（ATR-FTIR）.The O-H stretch vibration（νOH）,CH₂ asymmetrical stretching vibration（νasCH2）,CH₂ symmetrical stretching vibration（νsCH₂）,CH₂ scissoring vibration（δCH₂）,C-O stretch vibration（νC-O）,O-H in-plane bending vibration（δOH）,glucose skeleton vibration mode（νⅠ）and glucose skeleton breathing vibration（νⅢ）were found.The solid phase glucosesνⅠ and νⅢ had been discussed by two-dimensional infrared spectroscopy（2 D-IR）.Theα-D-glucopyranose andβ-D-glucopyranose were discoverd and influence of temperature change on solid glucose structure was researched by 2 D-IR also.更多还原
