Abstract

The spectral characteristics of prodigiosin in the visual range and the changes occurring in them through different concentration of the substance, polarity of solvent, and temperature have been studied. The conclusion has been reached that these changes are due to the existence of two forms of the pigment: monomeric - with a maximum at 460 mµ, and dimeric - with a maximum at 530 mµ. It is assumed that in certain conditions there may exist a trimeric form of the pigment. Data are being adduced in support of that assumption.
