WebJan 30, 2024 · This formula is the common form of the Beer-Lambert Law, although it can be also written in terms of intensities: \[ A=\log_{10} \left( \dfrac{I_o}{I} \right) = \epsilon l c \label{6} \] The constant \(\epsilon\) is called molar absorptivity or molar extinction coefficient and is a measure of the probability of the electronic transition. On ... WebApr 12, 2024 · Real deviations arise from changes in the refractive index of the analytical system; these changes will be significant only in high-absorbance differential measurements.The Beer-Lambert law is well obeyed by many substances at low to moderate concentrations.
