Diffuse Reflectance Spectroscopy — A Quantitative Technique for Characterizing Ligand Field Spectra
The theory of diffuse reflectance spectroscopy of compacted powders was placed on a quantitative basis by Melamed (1), who considered the total scattering transmission and absorotion of radiation from individual spherical particles. In spite of the limitations prevalent in a spherical particle model, Melamed was able to show that the absorption coefficient could be evaluated quantitatively from diffuse reflectance, but the errors could be as great as 25% even when the molar extinction coefficient was large.
