Theoretical extinction coefficient
Webb1 juli 2006 · This expression is identical to the “Lambert–Beer law” which is used to describe the radiation attenuation in homogeneous solutions which can written as (2) I = … WebbDeviation from the theoretical extinction coefficient was determined by calculating the experimental bias first, which is the difference between the mean experimental extinction coefficient and the theoretical extinction coefficient. The percent bias (%bias) was then calculated as (bias÷theoretical EC)×100.
