Spectroscopic analysis

Japanese: 分光分析 - ブンコウブンセキ
Spectroscopic analysis

When a substance is irradiated with electromagnetic waves, the interaction between the two causes primary radiation, secondary radiation, absorption, and diffraction phenomena. This is the general term for analysis that applies these spectroscopic phenomena to chemical analysis. Analysis that uses primary radiation is called emission spectroscopy, and in the gamma-ray to X-ray range, there are X-ray emission spectroscopy and gamma-ray spectrometry. ESCA is X-ray photoelectron spectrometry, which is a primary emission spectroscopy that measures and analyzes the energy of electrons emitted when a substance is excited with X-rays. In the ultraviolet to infrared range, there are emission spectroscopy, flame photometry, and absorption photometry. In the gamma-ray to X-ray range, there is X-ray fluorescence analysis, and in the ultraviolet to infrared range, there is fluorescence analysis. In the absorption range, there are X-ray absorption analysis, ultraviolet-visible spectrophotometry, and atomic absorption spectrometry, and in the far-infrared to microwave range, there is infrared spectroscopy and microwave spectroscopy. Other examples include X-ray diffraction analysis using X-rays and Raman spectroscopy.

物質に電磁波を照射すると,両者の相互作用によって,一次放射,二次放射,吸収,回折現象が現れる.これらの分光学的現象を化学分析に応用する分析の総称.一次放射を利用するものは発光分光分析といわれ,γ線~X線領域ではX線発光分光分析,γ線スペクトロメトリーなどがある.エスカ(ESCA)はX線光電子スペクトロメトリーであり,X線で物質を励起した際に放出される電子のエネルギーを測定し分析する,一次放射分光分析である.また,紫外部より赤外領域のものとしては,発光分光分析,炎光分析,吸光光度分析などがある.二次放射を利用するものでは,γ線~X線領域で蛍光X線分析,紫外~赤外領域で蛍光分析がある.吸収現象を利用するものとしては,X線吸収分析,紫外可視分光光度分析,原子吸光分析,また遠赤外~マイクロ波領域で赤外分光分析,マイクロ波分光分析などがある.そのほか,X線によるX線回折分析,またラマン分光分析などがある.
