These authors have shown that detrital organic matter, either terrestrial or aquatic, coming from different sources, could be described in terms of up to six generic organic components (carbohydrate, protein, lignin, lipid, “pure carbonyl”, and char), assuming that the experimental spectra of the organic matter could be reproduced from a linear combination of spectra of these six generic organic components.
