How To Calculate Molar Extinction Coefficient

How To Calculate Molar Extinction Coefficient. According to beer's law, a = εbc, where a is the absorbance, ε is the molar extinction coefficient, b is the path length of the cuvette and c is the concentration. Simple extinction coefficient is a measure of the rate of transmitted light via scattering and absorption for a medium.
