Deviations from beer's law

WebThe real deviations are considered to be fundamental as they represent real limitations to the law. The real deviation from the Beer’s law is based on the impact of the concentration of the solutions on the absorbance and molar absorptivity of the solution. When concentration of a solution changes by , there will be a change in the distance ... WebApr 18, 2024 · Beer's law assumes a linear dependence of absorbance on concentration, accordingly the index of absorption and the molar attenuation coefficient are material properties and the absorption cross section, including absorbance itself, must be additive if chemical interactions are excluded.
