SUMMARY The relative amounts of chlorophyll b ( C b ) and various chlorophyll a (C a ) forms in nine plant species were determined by computer analysis of low‐temperature absorption spectra. The results show that (a) the amount of C b is inversely related to the sum of the amounts of the bulk C a from both photosystems, (b) a direct correlation is likely to occur between the amounts of C b and the C a bands peaking around 685 nm and 640 nm, and (c) no correlation exists between the amounts of C b and the C a 662 and C a 695 forms. These data are interpreted to suggest that C b is capable of taking over the antenna function of the bulk C a , whereas it may occur in a complex carrying the C a 685 form as well.
