The absorption and rotatory properties of acridine orange-poly-Scarboxymethy1-Lcysteine system in water and in 0.2 M NaCl have been measured at different pH and polymer-to-dye mixing ratios. The absorption spectra indicate that the dyes are bound to the polymer in dimeric or highly aggregated forms.

## Abstract Circular dichroism and absorption spectra are measured on mixed solutions of acridine orange and poly(__S__βcarboxymethylβLβcysteine) at different pH and P/D mixing ratios. The observed circular dichroism spectra are classified into several types, mainly based on the number and sign of
The interaction of CuC1, with poly(Scarboxymethy1-L-cysteine) (poly[Cys(CH,COOH)]) and poly(Scarboxyethy1-L-cysteine) (poly[Cys(CzH,COOH)]) were studied by absorption spectra and circular dichroism (CD). On mixing CuClz with polypeptide solutions, absorption bands appeared at 32C-325 nm in both poly
The electronic absorption and circular dichroism spectra of the complex formed by acridine orange with poly-a,L-glutamic acid in the a-helix conformation have been measured in aqueous solution over a range of glutamate residue-to-dye ratios. Three Cotton effects (circular dichroism bands) associated
