Abstract
At least 3 forms of Triton X-100-solubilized bacteriochlorophyll a (BChl a) were characterized by UV/visible/near-IR absorption and CD [circular dichroism] spectra. One, absorbing at 770 nm, is similar to a monomeric solution in methanol. The 2 others have strongly red-shifted absorption peaks (860 and 930, 835 nm) and intense and complex CD bands in this region, indicative of strong interaction of at least 2 and 3 molecules of BChl a, respectively.Keywords
