↔The molar attenuation coefficient is a measurement of how strongly a chemical species attenuates light at a given wavelength. It is an intrinsic property of the species. The SI unit of molar attenuation coefficient is the square metre per mole, but in practice, it is usually taken as the M−1⋅cm−1 or the L⋅mol−1⋅cm−1.
↔Extinction coefficient refers to several different measures of the absorption of light in a medium: Attenuation coefficient, sometimes called "extinction coefficient" in meteorology or climatology. Mass extinction coefficient, how strongly a substance absorbs light at a given wavelength, per mass density.

The term molar extinction coefficient (ε) is a measure of how strongly a chemical species or substance absorbs light at a particular wavelength. ... The SI units of ε are m2/mol, but in practice they are usually taken as M-1cm-1
