It is the ratio of the sound energy absorbed by a material (E) to the overall sound energy previously spread and reaching the surface of the material (E0), also called sound absorption coefficient (α). If you would like to test your skills working with the Beer-Lambert Law then you might like to look at the Spectrophotometry tests at: A number of the class seem to have had a problem in understanding the relationship between the Beer-Lambert Law and a straight line, and working out the units of the extinction coefficient (ε).

Thus, given that absorbance is unitless, the units of molar absorptivity are L mol -1 cm -1. However, since the units of molar absorptivity is always the above, it is customarily reported without units. Example 2: Guanosine The absorption coefficient, α, is related to the extinction coefficient, k, by the following formula: α = 4 π k λ where λ is the wavelength.
