糖类物质的远红外谱有多个吸收峰 ,并且每种糖有其特征光谱。由于其相对强度顺序不同 ,我们可以选择前四个强峰用编号的方式来简单地区分各种糖。当形成络合物以后 ,出现金属氧振动的宽峰 ,说明远红外技术是一种判断络合物形成及探知其结构的有效手段 Far-infrared spectra of carbohydrates have multiple absorption peaks, and each sugar has its own characteristic spectrum. Because of their relative intensity order, we can choose the first four strong peaks in a numbered way to easily distinguish between the various sugars. When the complex is formed, there is a broad peak of metal oxygen vibration, indicating that far-infrared technology is an effective means to determine the formation of complexes and to detect their structure
