1.什么是光谱分析法?物质中的原子、分子等内部粒子永远处于运动状态,这种物质内部的运动会产生能级的跃迁并在外部以辐射、吸收或散射能量的形式表现出来,这种形式就是电磁辐射,而光谱也就是按照波长顺序排列的电磁辐射。光谱分析法属光学分析法的一类,它根据物质特征谱线的波长和强度对物质成分与结构进行定性、定量分析。光谱分析法一般分为发射光谱法,吸收光谱法和联合散射光谱法。发射光谱分析法又可分为:X 射线荧光光谱法,光学
1. What is spectroscopic analysis? The internal particles of matter, such as atoms, are always in motion. The movement of this material produces an energy level transition and is externally manifested as radiation, absorption or scattering of energy. The form is electromagnetic radiation, and the spectrum is the electromagnetic radiation in the order of the wavelengths. Spectroscopy French optical analysis of a class, it is based on the wavelength and intensity of the spectral lines of the material characteristics of the material composition and structure of qualitative and quantitative analysis. Spectroscopy is generally divided into emission spectroscopy, absorption spectroscopy and combined with scattering spectroscopy. Emission spectroscopy can be divided into: X-ray fluorescence spectrometry, optics
