Molar absorptivity - Wikipedia, the free encyclopedia
The Molar absorption coefficient , molar extinction coefficient , or molar absorptivity , is a measurement of how strongly a chemical species absorbs light at a given wavelength. It is an intrin...

Molar absorption coefficient (ε); Synonyms: Molar extinction coefficient, Molar absorptivity; "The recommended term for the absorbance for a molar concentration of a substance with a path length of l cm determined at a specific wavelength.

e is the molar absorbtivity with units of L mol-1 cm-1; b is the path length of the sample - that is, the path length of the cuvette in which the sample is contained. We will express this measurement in centimetres.

Because the absorbance of a sample will be proportional to its molar concentration in the sample cuvette, a corrected absorption value known as the molar absorptivity is used when comparing the spectra of different compounds.

The molar absorptivity of NADH at 340 nm has been determined by an indirect procedure in which high-purity glucose is phosphorylated by ATP in the presence of hexokinase, coupled to oxidation of the glucose- 6-phosphate by NAD+ in the presence of glucose-6-phosphate dehydrogenase.

The blank correction factor for the determined result with one light-absorbing reagent is epsilon P / (epsilon P - epsilon R), where epsilon R and epsilon P are the molar absorptivities of the reagent and the product, respectively.
