WebMar 12, 2015 · with R the absolute reflectance of the sample; A the molar absorption coefficient; and S the scattering coefficient. As the Kubelka-Munk relation assumes a thick infinitely diluted sample in a non-absorbing matrix with a diffuse-diffuse geometry, which was not the case here, the absolute values obtained for A/S do not have a physical meaning.
