拉曼光谱分析法
刘和文
Some Raman Advantages
Here are some reasons why someone would prefer to use Raman Spectroscopy.
• Non-destructive to samples (minimal sample prep)
• Higher temperature studies possible (don’t care about IR radiation)
• Easily examine low wavenumber region: 100 cm-1 readily achieved.
• Better microscopy; using visible light so can focus more tightly.
• Easy sample prep: water is an excellent solvent for Raman. Can probe sample through transparent containers (glass or plastic bag).
紫外吸收光谱分析法Ultraviolet spectrometry, UV

紫外吸收光谱的产生
紫外吸收光谱:分子价电子能级跃迁。
波长范围:100-800 nm.
远紫外光区: 100-200nm
近紫外光区: 200-400nm
可见光区:400-800nm
可用于结构鉴定和定量分析。
电子跃迁的同时,伴随着振动转动能级的跃迁;带状光谱。
