WebWhere A=absorbance, ԑ=extinction coefficient, c=concentration and l=path length. The Beer‐Lambert law draws a direct correlation between absorbance and concentration. While nucleic acids absorb at many wavelengths, they have a … WebEthanol absorbs very weakly at most wavelengths.) Solvent polarity and pH can affect the absorption spectrum of an organic compound. Tyrosine, for example, increases in absorption maxima and molar extinction coefficient when pH increases from 6 to 13 or when solvent polarity decreases.
