- Ultraviolet-VisibleSpectrum 紫外-可见光谱法也称紫外-可见分光光度法。是利 用物质的分子对紫外-可见光区辐射的吸收来进行定性、 定量及结构分析的方法。 一、紫外光谱的基本原理 分子中价电子经紫外或可见光照射时,电子从低能 级跃迁到高能级,此时电子就吸收了相应波长的光,这 样产生的吸收光谱叫紫外-可见光谱...

1.Kinetic degradation process of PAn films during aniline polymerization was in situ monitored by UV-Visible absorption spectrum.采用紫外可见吸收光谱法现场监测了苯胺电化学聚合时的动力学降解过程,简单、直观地显示了阳极电位、酸度和苯胺浓度对降解过程的影响,结果表明,阳极电位越正、酸度越强、苯胺浓度越大,聚...
When electromagnetic radiation in the ultraviolet (UV) or visible region of the spectrum is absorbed by a molecule, π or non‐bonding (n) electrons are promoted into antibonding orbitals. Because the main electron transitions are π→π* transitions, the absorption of energy in the UV or visib...
