Beer's Law

Beer's law describes the dependence of the absorption coefficient on the concentration of the substance (or the concentration of absorbing molecules in a non-absorbing solvent):

α = ε • C,

where α is the absorption coefficient, C is the concetration of absorbing molecules and ε is the molar absorption coefficient – ​​a constant that characterizes the absorbing substance and depends on the wavelength of the passing monochromatic radiation (it is a function of it).
