四、在化学上的应用 1.拉曼光谱与红外光谱虽然红外光谱和拉曼光谱均属分子光谱的范畴,研究的对象也大致相同,然而在产生光谱的机理、实验技术、光谱的解析等方面有较大的差别。因此,我们先将两种光谱作一简要的比较。样品的分子吸收红外光源产生红外吸收光谱,对单色光源的散射产生拉曼光谱。吸收光谱和散射光谱都与分子的振动,转动和品格振动等物理过程相关。因此,与红外光谱一样,拉曼光谱也是研究分子(或晶格)振动光谱和分子转动光谱的一种方法。
Fourth, the chemical application 1. Raman spectroscopy and infrared spectroscopy Although both infrared spectroscopy and Raman spectroscopy are the domain of molecular spectroscopy, the research object is roughly the same, but in the spectrum of the mechanism, experimental techniques, such as spectral analysis There is a big difference. Therefore, we first make a brief comparison of the two spectra. The molecules of the sample absorb the infrared light to produce the infrared absorption spectrum, and the scattering of the monochromatic light source produces the Raman spectrum. Both absorption and scattering spectra are related to physical processes such as molecular vibration, rotation and character vibration. Therefore, like infrared spectroscopy, Raman spectroscopy is also a method of studying the vibrational and molecular rotational spectra of molecules (or lattices).
