    • Diffuse reflectance spectra of powders are usually featureless because both weak and strong absorption bands lead to similar reflectance values. To obtain solution-like absorption spectra, the Kubelka-Munk transformation of diffuse reflectance spectra of highly diluted samples is required. See: (a) Kortüm, G. Trans. Faraday Soc. 1962, 58, 1624-1631
