物质的红外光谱分析方法是人所共知的。红外光谱分析有两种类型:分光的和不分光的。前者是将物质的吸收光谱全部记录下来,然后用标准光谱图对全光谱进行分析,进行物质各组分的定性或定量分析;后者是将仪器预先调谐成对某些特定波段的光辐射灵敏,从而对某一特定组分进行定量分析,这就是我们常说的红外线分析器。一、物质的红外吸收 The method of infrared spectral analysis of matter is well known. There are two types of IR spectroscopy: spectroscopic and non-spectroscopic. The former records all the absorption spectra of the material and then analyzes the whole spectrum with the standard spectrum to perform qualitative or quantitative analysis of the components of the material. The latter pre-tunes the instrument to the optical radiation of certain bands , So that a specific component for quantitative analysis, which is what we often say infrared analyzer. First, the material’s infrared absorption
