What Are The Features of UV Spectroscopy

Compare to other spectroscopy, ultraviolet spectroscopy has the following characteristics: 

1. The absorption spectrum of UV has higher sensitivity and lower detection limit. So it is commonly used in quantitative analysis of conjugated diolefine, and carbonyl compounds. 
2. Since ultraviolet region has shorter electromagnetic radiation wave length, and energy is larger, it can reflect the situation of the transition of the mid valence electron. UV spectroscopy is mainly used in the analysis of conjugated diolefine, carbonyl compounds, and the aromatic compounds. 
3. When the electron energy level changes, it is usually accompanied by vibration energy level transition, therefore the feature signal is fewer than others in the qualitative analysis. Besides, it has wider peak in the spectrum and the shape of the spectrum is simpler.
