## Abstract Circular dichroism and absorption spectra have been measured on solutions of acridine orange and poly(Lβglutamic acid) mixed at two molar ratios of carboxyl groupβtoβdye, P/D 25 and 0.8, and at different pH's. Characteristic circular dichroism is induced at the absorption bands of acrid
