absorption coefficient

https://doi.org/10.1351/goldbook.A00037
Linear decadic (\(a\),\(K\)) and Napierian absorption coefficients (\(\alpha \)) are equal to the corresponding @A00028@ divided by the optical path length through the sample. The molar absorption coefficients (decadic \(\varepsilon\), Napierian \(\kappa \)) are the linear absorption coefficients divided by the @A00295@.
