TīmeklisThe Beer-Lambert law is expressed as: A = εLc. where, A is the amount of light absorbed for a particular wavelength by the sample. ε is the molar extinction coefficient. L is the distance covered by the light through the solution. c is the concentration of the absorbing species. Following is an equation to solve for molar extinction coefficient:

Tīmeklis2024. gada 8. apr. · Lambert’s law states that the absorbance of the solution is directly proportional to the length of the sample of the solution through which the light passes. So mathematically, A = log10(I0/I) ~ l. A = εl. Where, A = Absorbance. l= Length of the sample solution. ε = Absorptivity or molar attenuation coefficient.
