Ratios, proportions, and mixtures of chlorophylls: Corrections to spectrophotometric methods and an approach to diagnosis

“…This reasoning is behind the methods of Moss () for determining Chl a and phaeophytin a, and Parkin and Brock () for mixtures of Chl a and bacteriochlorophyll d from green sulphur bacteria. Absorbance ratios have also been proposed to detect differences in carotenoid/chlorophyll proportions as indicators of ecosystem diversity, maturity or trophic status (Margalef ; Winner ; Sigareva and Lyashenko ).…”
