Absorption spectrum of Rhodospirillum rubout pigment complexes in basic solvents . — The adsorption and aggregation of bacteriochlorophyll are studied in various polar solvents, at different concentrations. It is shown that 3 absorption bands exist in these conditions, duplicating 3 of the absorption bands found in vivo : the 772 nin, the 830 nm and the 890 nm‐bands. The 800 nm‐band cannot be formed in vitro . The relations between the respective concentrations of the 3 states of bacteriochlorophyll found In vitro are calculated and discussed.
