Both the absorption and fluorescence show strong bathochromic shift effect with the increase in the polarity of solvents.

这些化合物随着溶剂极性的增加，吸收峰和荧光峰都表现出强烈的红移。

The absorption of doping polyaniline becomes very intense and the absorption peak generates bathochromic shift in ultraviolet visible absorption spectrum.

紫外-可见吸收光谱表明，掺杂态聚苯胺的吸收峰变宽而且发生红移。
