实验测量了木糖醇的拉曼光谱和红外光谱,在相关文献的帮助下,对其谱带进行了初步指认。在拉曼光谱中,1000cm-1～1110cm-1之间的中等强度振动属于C-O伸缩振动和H-C-O弯曲振动。850cm-1到920cm-1之间的振动属于C-C伸缩振动。羟基面内弯曲振动在红外吸收光谱中出现在1300～1500cm-1,O-H的变形振动δO-H出现在1420～1380cm-1。 The Raman spectra and infrared spectra of xylitol were measured experimentally, and their bands were preliminarily identified with the help of relevant literature. In the Raman spectrum, moderate intensity vibrations between 1000 cm-1 and 1110 cm-1 belong to C-O stretching vibration and H-C-O bending vibration. Vibration between 850 cm-1 and 920 cm-1 belongs to C-C stretching vibration. The in-plane flexural vibrations appear in the range of 1300-1500 cm-1 in the infrared absorption spectrum, and the δO-H of O-H occurs at 1420-1380 cm-1.
