分子消光系数是被测溶液对光的吸收大小值； 被测溶液浓度高，溶液显色后颜色深，对光吸收大，光透射率低，反之就小。同种溶液对不同波长的光谱有不同的吸收峰。
测定了在水、乙醇、二氧六环中的紫外吸收光谱与克分子消光系数以及萤光光谱和量子产率。
The ultraviolet absorption spectra and molar extinction coefficients, fluorescent spectra as well as quantum yields of nucleoside hydrazones in water, ethanol and dioxane were measured.
由式(1)化合物形成的偶氮染料具有极佳的色调，高分子消光系数和良好的贮存稳定性，因此，被用作成像染料以及着色剂。
Azo dyestuff formed by (1) has great color tone, macromolecule extinction coefficient and good storage stability, so it can be made into imaging dye stuff and colorant.
分子的消光系数等于入射光和透射光强度对数的比。
