Is there a link between absorbance and extinction coefficient?
The absorbance of a molecule is directly proportional to its extinction coeficient. The higher the extinction coefficient, the stronger the molecules absorbance will be. Briefly, the equation to calculate absorbance is A = ebc Where; A= absorbance b= path length of the cell/sample container c= concetration of analyte in molarity e = extinction coeficient (units of liters per mole*cm, i.e., L/(mol*cm) ) the extinction coefficient, e, is also referred to as the molar absorbtivity or molar extinction coeficient. Hope that explanation helps.
