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 ... WebThe real deviations are considered to be fundamental as they represent real limitations to the law.
