In chemistry, molar absorptivity is defined as a measure of a chemical's ability to absorb light at a specified wavelength. The molar absorptivity coefficient, Îµ, depends on the chemical species; actual absorption depends on chemical concentration and the path length. These variables are used in the Beer-Lambert Law. Molar absorptivity also is known as the molar extinction coefficient and the molar absorption coefficient. The Beer-Lambert Law is an equation relating absorption to chemical concentration, path length and molar absorptivity. Mathematically, the Beer-Lambert Law can be expressed as A = Îµcl.
